Internships and Mentors

I'm back observing with Magellan II at Las Campanas Observatory, this time with the Planet Finder Spectrograph, which I've blogged about here before. I came straight to LCO from the 229th American Astronomical Society (AAS) meeting in Dallas, TX, where I was reminded of how overwhelming yet thrilling these huge astronomical gatherings are. It took me back to my times attending as an undergraduate student; many summer internship programs, including the one newly started at Carnegie Observatories and one I just learned about for Argentinian students at Las Campanas, provide students with funding to attend the winter AAS. Attending the meeting and presenting a poster was, for me, an eye-opening and very exciting experience, a window into the world of professional astronomy. It is the culmination of a summer, and sometimes fall semester, of authentic astronomy research that is really the best way for students to decide whether they want to pursue a career in astronomy or astrophysics after college. Such research internships are often the start of strong friendships with other interns, and can also be the start of the incredibly important mentoring relationships that carry students (at least, they carried and continue to carry me) through their careers.  To those hosting students this summer, think back to how formative this experience was for you in your career, and about how you can make this summer the best it can be for your student(s). For those applying, my advice is to take advantage of the opportunity to work on something you haven't before, and soak up all the knowledge from your fellow interns that you can. I learned just as much, if not more, from my intern buddies during my REUs, especially about the practice of astronomy (versus the content knowledge).




Maria Mitchell Observatory summer interns (I'm down in front), and my research mentor Jackie Milingo, at Kitt Peak Observatory during the summer of 2006. I worked with Jackie studying chemical abundances measured in planetary nebulae.

Phillips Auditorium at Harvard in the summer of 2007. That summer I measured different types of emissions (optical, IR, X-Ray) in merging galaxies to better understand what controlled star-formation and AGN activity. 

At the AAS meeting, I was pleasantly surprised to run into one of my mentors, Michelle Edwards, whom I met in graduate school at the University of Arizona where she is a Support Astronomer for the Large Binocular Telescope. Michelle and I didn't work directly together very much, but she was the person who turned me on to instrumentation, and cheered me on during the last few years of graduate school when I was struggling. It was from Michelle that I realized working at an observatory was a career option, one that I very much still consider as a possible path. Michelle and I are still close, and when I saw here across the large poster hall at the AAS meeting, I yelled out her name and ran over to give her a big hug. Although I'm no longer a student, I still go to Michelle for advice and support, and now I feel like I can support her, too. Mentors aren't always you're friends, but I have been lucky enough to become friends with most of mine.

The person who has mentored me the longest is Alycia Weinberger, who has written blog posts here before. I started working with Alycia during my senior year of college for my honors thesis, reducing and analyzing spectra from the MIKE instrument (which I use now in my postdoc!) of young stars with disks of gas and dust around them that we think are the sites of planet formation. Working with Alycia was an experience that kept me going through graduate school -- I thought if I could only make it through and get back to DTM, it would all be worth it. Lucky for me, I got the chance to go back for my postdoc, during which Alycia has continued to be a great mentor and also grown into a great friend. And now we're collaborating again on a few observing projects!

Alycia's advice comes from years of being successful in astronomy, pushing the fields of young stars and planet formation forward with new observations and observational techniques, and also from years of mentoring other young women like me. In fact, while interning at Carnegie DTM, I also met Mercedes Lopez-Morales, whom I went observing with right after graduating college on my first trip to Magellan and who has also been mentored by Alycia. Mercedes is now at the Center for Astrophysics at Harvard, and our work overlaps -- we are both using radial velocity spectrographs to measure the masses of transiting planets! Mercedes has become a mentor to me, too, guiding me through the many twists and turns in the field of exoplanets, offering advice about science projects and career choices, and, like Alycia, serving as a role model who balances an amazing career with mentoring students and having a family.

This was taken at a recent Giant Magellan Telescope science meeting in Asilomar, California.

You may be noticing a pattern...almost all of my mentors and advisors have been women! This was also the case during my PhD, where I had two co-advisors, both of whom were women. I honestly have not tried to do this on purpose, but I haven't avoided it either. Sometimes I wonder what this means about my personality and work style...but I am constantly thankful for the compassion, patience, and guidance these women have shown me.

In science, like in the rest of the society, women are still not on equal footing. I think any close mentoring relationship is important, and some of my best mentors right now are men who have taught me a lot and are incredibly supportive of my ideas (even when I make mistakes). But I have found that those relationships I have with fellow women are enhanced by our shared experience of needing to work a little harder, speak a little louder, and have the confidence to stand up for ourselves, even when we're the only woman in the room. I have these mentoring relationships with women to thank for where I am today, and wherever I end up in the future (and I really haven't done them justice here, apologies!). They saw/see something in me that I did/do not see myself.

Remembering Vera

On December 25, 2016, the great astronomer Vera Rubin passed away, surrounded by her family. Vera helped discover the still-mysterious presence of dark matter in the universe in the 1970s, when the largest telescope in the world was about 5m in diameter (now we are working to build telescopes five to six times that size). Her creativity and persistence and ingenuity advanced astronomy into a new age of exploration and trying to understand the history of everything. At the same time she demonstrated the amazing potential and the necessity of women participating in science. Vera was a vocal proponent of equity for women in science, for women's rights in larger society, and a mentor and inspiration to many, many women scientists at all career stages. You can read more about her life and her work here and here (both in her own words), here, here, here, and here.

Frustratingly and sadly, Vera has not and will not be awarded a Nobel Prize for her ground-breaking and trail-blazing work. But we should remember her for the awesome scientist and person she was, Nobel or not, and can honor her by continuing to share memories and stories of her life and work. We started an open document for those who knew Vera, who drew courage and strength from her resilience, who were deeply touched by her compassion and humanity can share their memories of her. This is also a window into the day-to-day difference she made, for those who did not have the privilege of knowing her.

Thank you, Vera.

Bring Your Mom to Work Day(s)

Every since I started observing at Las Campanas, I've talked to my mom about how amazing it is -- the views, the facilities, the people, the food. She loves hearing about my adventures and seeing pictures, and closely follows Yuri Beletsky (whose pictures surpass mine by far). She also has a deep appreciation for nature and how awesome the universe is. Thus it was my great pleasure to treat her to a trip to Las Campanas! I'm here for a two-night MIKE run to observe stars that host cool Jupiter exoplanets. I'm working with Jonathan Fortney and Daniel Thorngren to understand how the composition of these stars may be related to the heavy element mass locked up in their gas giant planets. You can read more about the project in Daniel's paper.

What this post is mostly about is Las Campanas from my mom's perspective. Here is our mini interview:


1. What brings you to Las Campanas?
First and foremost, to spend time with my daughter, Johanna, watching her work. Secondly, to see the night sky. I have seen pictures, but I wanted to see the night sky and stars with my own eyes. And the empanadas. Cannot forget the empanadas! 



2. How was your travel to the telescopes?
The travel was long! I traveled from Harrisburg, PA. Johanna and I had adventures flying from Miami to La Serena, sleeping in little pods on the plane. But the drive up to the telescopes was amazing- the road kept getting steeper and steeper until there was no more road. We reached the top of the earth! I kept thinking about all of the amazing people who build these telescopes and how challenging their journey must have been.

 3. What were you most looking forward to? Has that happened?
I was most looking forward to seeing the Milky Way. We saw it last night and it was amazing. Dizzying, in fact! A lifetime event for me. And watching the sunset was unlike anything I have ever seen. Ribbons of reds and oranges with no cloud interference. And SO MANY STARS! I will never forget that night sky. Lastly, hearing about Johanna's adventures so far and her ideas about her future. She inspires me!



4. Has anything surprised you so far?
The temperature has surprised me -- I expected it to be cooler during the day, but it is actually quite pleasant. Another thing that surprised me is how astronomers "share" data and "time" with each other. Johanna is actually using some of her time tonight to "pay back" a colleague who got some observations for her earlier in the year. It is a concept that is not common across other sciences -- folks
can be territorial about their data. 
 


5. What have you done at the Observatory so far?
We took a nice long walk this morning and I got to see all of the telescopes. I heard a bit about the history behind each one, which I enjoyed. I also saw some new flora and fauna, which is always of interest to me. I also have enjoyed the meals at Las Campanas and was happy to be here for Empanada Sunday! I am looking forward to seeing Johanna in action tonight as she observes. But the night sky and time with my daughter are the highlights so far.

6. How would you describe Las Campanas Observatory to other people? What does astronomical observing look like (to someone who does not do it for a living)?
It is not what I thought it would be like. There is a lot of sitting at computers doing compter-y stuff. But last night, I was witness to some exciting science happen. One of Johanna's colleagues found some important stuff for his research, and while I was not clear on what it was, there was an excitement in the room that was palpable. I also am now aware that the observing runs are just PART of the work. For example, I am spending the afternoon with my daughter as she "calibrates" the instrument she will be using tonight. Then she does the observations, then the analysis, then the writing of the paper. I am learning that astronomical observing is just part of a larger process.


7. Any tips for first-timers?
Ask lots of questions, drink lots of water, rest after walking uphill, take lots of pictures. And look up at the night sky every chance you get. The excitement starts after sun down! 


 
Viscacha at sunset!

8. Anything else you'd like to share?
My gratitude for the staff and scientists who allowed me to come and be a part of this awesome experience.

First Time in the Southern Hemisphere!


This trip had a lot of first for me: first time going observing at a major observatory, first time in the Southern Hemisphere, first time taking infrared spectra and images, and last but not least first time doing it on my own after only two days of training. I was so excited when I first got to Chile. There was so much to see and especially when I got to Las Campanas all I wanted to do was look around. When I arrived I was under the impression that we were going to start observing that night, but to my surprise we didn’t start until the next day, which was great for me since I was exhausted after the long flight.  

On day one of observing, after lunch I went up to Baade to meet my advisor, Jackie Faherty, to start calibrations for FIRE and Fourstar. Learning about calibrations was simple enough, especially since all of the information could be found in previous nights logs. After calibrations I had some free time to explore before dinner.

On the way up I saw this guy. We had a stare down, until he walked away.
After taking calibrations I found some of these creatures.

The first I observed using FIRE on the Baade telescope. When I saw the telescope for the first time my first thought was “This is SOOO big. I feel so tiny!”. You can see me to scale with the mirror, no joke this telescope is enormous and I can’t even fathom how crazy it will be to look at the GMT. 



The night wasn’t too intense, but it was a lot to take in knowing that in two days I would be on my own. At first I made a few mistakes, mostly incorrect filenames, but as the night went on I started to feel more comfortable with the instrument. Also, having a ton of notes on the processes helped to ease my nervousness about the upcoming night alone.  The conditions were’t the best but we managed to get a fair amount of targets done.




On the second night I used both FIRE and FourStar. FourStar was much simpler to use, which made me less worried about the next night, since I would be using both instruments. The conditions were great, so I got lots more experience using FIRE and I managed to make very few errors over the night. I was quite proud about that! At the end of the night Jackie and I discussed the plan for the next night. At that point I felt fairly comfortable to be left on my own with my game plan in hand, I headed off for bed.


This brings us up to tonight where I am alone. Eek! Calibrations made me a bit nervous, since the first question I got from the telescope operator was about what to do with the mirror cover. He hadn’t asked us previously so I felt unsure about what to do, but I once I thought about it the answer was clear and my fears of messing up calibrations went away. At dinner I met the person who was going to be on Baade after me. He was very curious to see how FourStar works, so he decided to join me for part of the night. The conditions needed up being perfect and the night was smooth sailing! Now I just need to get all of this data transferred and then off for a nap!

An all-women observing run at Gemini

Hello Las Campanas Belles!  While I spend most of my time in Chile at LCO, this week I was in Chile observing on a telescope a couple hundred kilometers to the south: the Gemini South telescope at Cerro Pachon.  I blogged about it at Cosmic Diary/ Gemini Planet Imager, but I wanted to post a little about it here!

I had never been on an all-women observing run before, and neither had any of the 5 of us!  Myself, MagAO users Kate Follette, Kim Ward-Duong, and Jenny Patience, and student Sarah Blunt were at Gemini to look for planets using the Gemini Planet Imager (GPI).  It's winter in Chile and we had some cloudy weather as well as a bit of snow, but we squeezed in observations whenever we could.  Check out the link above to read more about it!

And here is a picture of the women GPIES observers:




Here is the Gemini dome with some beautiful but not-good-for-observing clouds:


And they have some of the same animals at Gemini, like this cute little zorro near the dorms!

Chile-US Astronomy Education Outreach Summit visits Las Campanas Observatory

Amanda Kocz is Communications Officer for the Giant Magellan Telescope Organization. Opinions in this post are her own.
A few weeks ago, I was lucky enough to take part in the second Chile-US Astronomy Education Outreach Summit, held in La Serena, Chile.

Outreach summit participants at Magellan.

The purpose of the summit was to bring together fifty or so astronomy outreach professionals, teachers and administrators to work on revising the draft of the Roadmap to the Stars (not available online yet - still a draft). This document, written at the first Summit in 2015, outlines the current state and the future of astronomy outreach in Chile. The summit was also a great opportunity to network, to share ideas and to make connections with our counterparts.

I was there representing the Giant Magellan Telescope Organization, which meant I had the good fortune to spend the week with my colleague, Dr. Miguel Roth, former Director of Las Campanas Observatory (LCO), and current Chile Representative for the GMT.

The first day of the summit was a fieldtrip to LCO. On the bus I got to know Pablo Álvarez, who is working on a project called Astroturismo Chile, which is assessing the quality and competitiveness of astrotourism in Chile. 

As we reached the turn-off from the Pan American Highway, I immediately recognized the landscape in the distance. Looking from left to right we could see the du Pont, the Magellans, and the GMT site. The driver stopped the bus, and we all got off to check it out. Mark Philips, current LCO Director, explained what we were seeing.

Then we began the somewhat tedious, bumpy and dusty journey to the summit. As we got closer, the two instrument towers on the GMT summit became more visible, and soon we reached the turn off to the site. We couldn’t pay it a visit due to construction work, but I was excited to be there again. (Last time I was there, it was the GMT Groundbreaking Ceremony in November 2015.)
The instrument towers visible on the GMT site.
We continued to the far end of LCO to the du Pont Telescope. Commissioned in the mid-1970s, it was used for wide-field photography on photographic plates. It is now being used for a new project, APOGEE, a fiber-fed spectrograph designed to do a southern sky survey of the Milky Way.
Mark Phillips tells the group about the du Pont Telescope.
From our vantage point at du Pont we could see all of LCO’s telescopes. In the middle distance was the Swope, named after Henrietta Swope, a famous astronomer who was also a philanthropist and gave $250,000 to Carnegie to build the telescope.
We could also see three site testing telescopes that are used to measure the site’s seeing. Also in the middle was the Ogle, a 1.3m telescope operated by the University of Warsaw for gravitational lensing observations.

All of this information was coming at us via a bilingual comedy double act between Mark and Miguel. Mark was doing the English, and Miguel was doing the Spanish, except when they forgot which was their native language and switched. The explanations became a competition as each of them relayed ever more outlandish stories.
Mark Phillips and Miguel Roth keep the crowd entertained.
Soon it was lunchtime, and we sat on long benches in the dining room getting to know our colleagues. I chatted with Valentina Rodríguez and Laura Ventura from ESO, feeling quite inadequate at my lack of Spanish.
After lunch we were taken to see the Magellans, and we headed up the stairs into the control room of the Baade telescope. Mark and Miguel continued their comedy routine before we were taken inside the dome to stand face to face with the 6.5 meter mirror.
Miguel Roth tells another elaborate story inside the Baade control room.
The explanations and descriptions of the telescope and its mirror came thick and fast from Miguel and Mark but everyone seemed more excited about getting their photo taken with the mirror. We were also lucky enough to have time to visit the coating chamber in between the two telescopes. Each year one of the mirrors is stripped and realuminized in this room (video here).

Suitably telescoped-out we rejoined our bus and headed a little way down the hill for a group shot with the GMT site in the background. Then we hit the road for the two hour drive back to La Serena.

This outing was the first of many highlights of the Summit. I won’t forget the experience of revising the Roadmap document, huddled around a translator who was doing an amazing job of keeping us non-Spanish-speakers in the loop. I was appreciative of the opportunity to meet and get to know the many enthusiastic astronomy outreach professionals who attended (especially Suzanne Jacoby from LSST and Sandi Preston from McDonald Observatory).

What I learned was that there are more great ideas for engaging the public with astronomy than I could have imagined, and that an enormous amount of work is being done in Chile already. The country hosts a large fraction of the world's astronomical light gathering capability, and the hope is that one day the world will come to know Chile for its astronomy.

I’m very grateful to the Summit organizers for such a productive and well-run event, and for inviting me to attend.
