News from the Department (2016)
- Graduate student Ashlee Wilkins was interviewed in a heart warming article that was featured in the Fall 2016 issue of Odyssey Magazine. The article highlighted the Graduate Resources Advancing Diversity with Maryland Astronomy and Physics (GRAD-MAP) program and other diversity efforts by Ashlee and the UMD astronomy department.
- A new study led by Professor Douglas Hamilton suggests that Sputnik Planitia, also known as the "icy heart" on Pluto, formed early in Pluto's history and that its attributes are consequences of evolutionary processes. Dr. Hamilton's paper was published in Nature and was chosen by Astrobiology Magazine as their #1 story of 2016! Find the full CMNS release here.
- Professors Dennis Bodewits and Mike A'Hearn co-authored a paper that was featured on the AAS website. The study used images of comet 67P/Churymov-Gerasimenko to study the chemical composition of its nucleus and how it may have changed over time.
- Emily Garhart was selected to receive the 2016 USRA Thomas R. McGetchin Memorial Scholarship Award. She was selected from among 59 eligible applicants for one of the 5 USRA scholarship awards this year. A big congrats to Emily!
- Professor Douglas Hamilton co-authored a paper, "Tidal Evolution of the Moon from a High-Obliquity, High-Angular-Momentum Earth," in the Advance Online edition of Nature. Using numerical models of the moon's explosive formation, Hamilton and his co-authors found that the impact that formed the moon could have caused calamitous changes to Earth's rotation and the tilt of its spin axis.

- A NASA press release featured grad student Krista Smith's work for the Kepler-Swift Active Galaxies and Stars Survey (KSwAGS). Her team combined observations from the Kepler and Swift space missions (Krista led the Swift analysis), and they conducted followup observations of unusual stars with high X-ray output. They discovered that these stars spin so quickly that they are distorted into 'pumpkin' shapes! These stars are believed to be the result of closely-orbiting binary stars which have merged together.
- Professor Suvi Gezari has won the CMNS Board of Visitors Junior Faculty Award. Suvi is a world leader in time-domain astronomy, a field identified by the NRC Decadal Panel as a "key frontier discovery area." She is internationally recognized for her work on tidal disruption events (TDEs), in which a star is tidally torn apart by a supermassive black hole. She pioneered the technique of using the variations in light emitted to estimate the key black hole parameters, mass and spin. Congratulations!
- Drs. Dan Gershman and Levon Avanov are co-authors of a new Physical Review Letters article about observations from the Magnetospheric Multiscale (MMS) spacecraft.

- Research scientists Ed Shaya, Rob Olling, and other team members identified the first-ever "shock breakout" of a supernova in visible light. The 20-minute breakout occurs when a shockwave originating in the core of a dying star reaches the star's surface. The images were taken by the Kepler Space Telescope, which was designed to hunt for exoplanets, but the team creatively took advantage of the telescope's rapidly repeating observations to find stars in the process of exploding into supernovae. For details, see the UMD Right Now news release.
- Alum Dheeraj Pasham (Ph.D. '14) is one of 13 people selected for an Einstein Fellowship, one of the most prestigious postdoc fellowship programs in astronomy. Dr. Pasham receives full support for 3 years to work at an institute of his choosing. He will be based at MIT, where he plans to apply and extend his expertise in time series analysis to (1) identify and weigh intermediate-mass black holes, and (2) address the many open questions concerning the tidal disruption of stars by supermassive and intermediate-mass black holes.
- Our very own Cole Miller has published a Nature News and Views article summarizing the LIGO gravitational wave detection. See how else UMD Astronomy ties into this incredible discovery from our story earlier this month.
