    Andrea Antoni

    I am a third-year graduate student in astronomy.  I work with Eliot Quataert studying the deaths of massive stars in weak or failed explosions in order to understand the observational signatures of black hole birth.

    I earned a B.S. in Physics (Astrophysics) with Highest Honors from the University of California, Santa Cruz in August 2018 where I was a Regents Scholar and a Barry Goldwater Scholar.  At UCSC, I worked with Enrico Ramirez-Ruiz and Morgan MacLeod studying the common envelope phase in the formation of close binaries as well as the general hydrodynamical problem of the drag and accretion experienced by binaries embedded in gases.

    I am a first-generation college student and I was introduced to physics at community college.  Participating in the Lamat REU the summer before transferring to UCSC was critical to my path to grad school because it mentors at a crucial time.  I am a coordinator for POWER Bay-Area, a mentoring program and workshop series for East Bay community college students.  If you’d like to get involved, please reach out.

    I am a first-year graduate student in astronomy. I graduated from Harvard University in May 2018 with an A.B. in Astrophysics and Physics. At Harvard, I worked with Dr. John ZuHone on investigating the effect of magnetic fields on gas dynamics in the cores of galaxy cluster mergers by using magnetohydrodynamic simulations generated with FLASH. Currently, I am working with Dr. Andrew Siemion and Breakthrough Listen to search for ISM-scintillated narrow band signals in radio time-frequency data with convolutional neural nets. I'm at desk 202A!

    As a PhD student at UC Berkeley in observational cosmology, I develop scalable pipelines to automatically detect galaxies in terabytes of multi-color imaging data. My team has spent the last four years collecting about 100 TBs of images using three professional (2-4 meter mirror) telescopes. The primary codebase I work on has detected and modeled about 1 billion galaxies and stars in this data set. After my PhD, I want to use the image analysis, high performance computing, machine learning, and statistics I've learned to solve real-world problems in society.

    I attended college at the University of Chicago, where I graduated in 2017 with a BA in Physics and a specialization in Astrophysics. While in college, I had the pleasure of working on a variety of astrophysics-related projects. These projects involved, for instance, studying Transit Timing Variations in the orbits of rocky exoplanets, simulating exoplanet migration and the occurrence of “hot Earths,” and modeling dust transport in protoplanetary disks.

    I am final year graduate student, working with Dr. Aaron Parsons on the correlator pipelines for current and future generation radio telescopes. The Hydrogen Epoch of Reionization Array (HERA) is a radio interferometer currently being built in South Africa, for measuring the power spectrum of the red-shifted 21cm neutral hydrogen signal. I spent a major part of my graduate school on building the correlator pipeline for this 350 antenna array. You can find a detailed description of this work on my Github website.

    I am also working on calibration algorithms for the next generation of correlators that might be built for arrays with more than 10,000 elements. More details of this work are available in this publication.

    Before graduate school, I went to Birla Institute of Technology and Science in the remote college town of Pilani in Rajasthan. There, in addition to developing liberal views, I obtained a double degree in Electronics Engineering and Physics. This mixture of courses drew me to instrumentation for radio astronomy and I did numerous small projects in this domain throughout undergrad. I spent the summer after my junior year in Germany, working on an instrument for the Effelsberg Radio Telescope on the DAAD scholarship program. For my final year thesis, I worked on upgrading the Ooty Radio Telescope to a digital system. To this measure, I wrote a software, Intel IPP based, polyphase filterbank and file writing pipeline.

    I am a second-year graduate student in astronomy. I work with Dan Weisz on massive metal-poor stars in the local group.

    Before Berkeley, I earned my B.Sc. in Physics and Mathematics at MIT in 2019. I worked on a variety of projects surrounding the early universe. I worked with Anna Frebel to understand metal-poor stars and neutron capture processes, and with Alan Guth on hybrid inflation and primordial black holes.

    Besides research, I am excited about outreach events, science communication and astrophotography.

    I am a recent graduate from Berkeley as of August 2018. My thesis project focused on comparing planets in binary star systems to those in single star systems, within a volume-limited sample of nearby G- and K-type stars. I used the ShaneAO system on the 3-meter Shane Telescope at Lick Observatory and the DSSI Speckle Camera on the WIYN 3.5-meter telescope at Kitt Peak to obtain high-resolution images of my bright sample stars, searching for high-contrast and close-in binary systems. I also used Keck-HIRES and the Automated Planet Finder to search for planets around the same sample of host stars. My goal was to perform a direct comparison between the planet populations in single versus binary stellar systems. I found that wide stellar companions (separations > 100 AU) do not seem to strongly affect the formation and evolution of giant planets. However, among the closer binaries surveyed with the radial velocity technique in my project, there were no definitive planet detections. This indicates that the closer stellar companions likely have a negative impact on planet formation and survival.

    I spent the spring and summer semesters of 2015 participating in the IPAC Visiting Graduate Student Fellowship program at Caltech. At IPAC, I worked with David Ciardi to apply high-resolution imaging data of Kepler planet host stars toward understanding the impact of stellar multiplicity on the inferred planetary radii of transiting exoplanets.

    Before becoming a graduate student at Berkeley, I was an undergraduate at Cornell University, where I worked with Terry Herter on FORCAST/SOFIA data of W3(OH), an ultra-compact HII region surrounding a newly formed massive star.

Fascinated by the final moments of a star’s life before death, my research focuses on winding back the cosmic clock to understand how certain stars produce the various supernovae observed today. I currently work with Prof. Raffaella Margutti on combining multi-wavelength observations (radio to X-ray) of a variety of supernova types to create a complete picture of the final stages of stellar instability and mass-loss before explosion.

    I am a graduate student in the Department of Astronomy at UC Berkeley. I am interested in finding isolated stellar mass black holes in the Milky Way with astrometric microlensing. 

    I graduated from MIT in 2017 with a bachelor's degree in math and physics. During my time there, I had the opportunity to do research in the Center for Theoretical Physics with Professor Tracy Slatyer, studying the distribution of pulsars "kicked" out from the galactic disc, and with Professor Alan Guth, studying hybrid inflation and primordial black holes. 

    Aside from research, I also enjoy participating in outreach events with the department. The picture (courtesy of Carina Cheng) is from Discovery Day at AT&T Park in San Francisco. It's a demonstration of how telescope mirrors focus light, which allows astronomers to see faint objects. (The demo is also great for roasting marshmallows!)
