Research Corporation Backs a Radical New Approach to Astronomical Imaging

August 25, 2021

A 12-megapixel digital camera can capture an image composed of roughly 12 million pieces of information and is all most of us need to take stunning vacation photos or family portraits suitable for framing. However, if you’re an astronomer taking detailed images of celestial bodies that are thousands to millions of light years away, it’s nowhere near good enough. But thanks to a Cottrell SEED Award from the Research Corporation for Scientific Advancement, UVA astronomer Steven Majewski may be one step closer to developing a technology that makes taking vivid panoramic snapshots of distant stars and galaxies something more than just the stuff of science fiction.  More here: https://www.as.virginia.edu/news/research-corporation-backs-radical-new-...

Amina Diop named as first John F. Angle Graduate Fellow in Astronomy

May 20, 2021

The Astronomy Department is pleased to announce that Amina Diop has been selected as the first John F. Angle Graduate Fellow in Astronomy. The Angle Fellowships are funded by a gift from Carol Angle and Fritz Angle. They honor Dr. John F. Angle MD (below), who is a nationally and internationally recognized leader in vascular and interventional radiology at UVa. He specializes in minimally invasive techniques to treat peripheral arterial disease, aortic aneurysm disease, venous insufficiency, venous thromboembolic disease, dialysis access maintenance, and cancerous tumors.

Amina Diop is entering UVa as a new Ph.D. graduate student this fall. She got her BA in Astrophysics & Arabic from Williams College, with a semester at the University College London. Amina is from Senegal, and has studied Entrepreneurship, Leadership, Math and Physics at the African Leadership Academy in Johannesburg, South Africa. Her research interests are astrochemistry and protoplanetary disks. For the last two years she has been working on an extensive research project, investigating the vertical structure of turbulence in the protoplanetary disk around the young star DM Tau. Amina modelled the emission from the molecular ion N2H+ coming from the disk. She won the Beth Brown Memorial Award for her poster on this subject at the National Society of Black Physicists’ annual meeting earlier this year. Nitya Kallivayalil, co-Chair of Graduate Admissions said, “I was really impressed with Amina’s poster at the conference, and upon chatting with her further, I found out that her true passion lies in radio astronomy, and that she wants to be a radio astronomer. I think she has made a wise decision, therefore, to come to UVa for graduate school, and we are thrilled that she chose us.” Amina also has extensive teaching and outreach experience and is interested in helping minority students both in the US and overseas.

The McCullough Scholarship Prize
This scholarship recognizes the outstanding academic and research work of a second-year undergraduate student in Astronomy or Astronomy-Physics. It is named for Dr. Timothy P. McCullough who who was a radio astronomer at the Naval Research Laboratory in Washington, DC. Dr. McCullough made some of the first radio measurements of many objects in the Solar System. The scholarship was established by his son, Gene McCullough, who is a U.Va. alumnus, graduating with a degree in Physics and
being in the first contingent of Echols Scholars at U.Va. As the scholarship was established only last summer(in 2019) after graduation, the winner of last year has not been yet announced publicly. So both last year and this year's winner are announced here. 2019's winner was Camryn Phillips. She did research with Prof Phil Arras on using the satellite Kepler data to  look for tidal effects caused by planets on their stars. 2020's winner is James Staeben. He worked with Prof Craig Sarazin on analyzing Chandra X-ray observations of clusters of galaxies, shedding light on how they form by merging processes. The award includes a $1000 prize and a certificate.

 

The Vyssotsky Prize
The Vyssotsky Prize recognizes an outstanding third year undergraduate student in Astronomy or Astronomy-Physics. Professor Alexander Vyssotsky worked at McCormick Observatory for 35 years beginning in 1923. This year, the Vyssotsky Prize goes to Josef Zimmerman. Josef did research with Physics Prof Kent Yagi on the study of the properties of nuclear matter in neutron stars using gravitational wave and X-ray observations. The Vyssotsky Prize consists of a certificate and a $1,000 fund for professional travel during the student's 4th year, such as an observing trip, or a presentation at a conference.

 

D. Nelson Limber Award
The D. Nelson Limber Award recognizes outstanding accomplishments in course work and astrophysical research by a graduating undergraduate major or majors. The award is named for Nelson Limber, who was a professor in the Astronomy Department at the University of Virginia and a leading figure in the theoretical study of the interstellar medium and galaxy clustering. This year, the Limber Award goes jointly to Megan Kenny and Eric Rohr. Both have excelled in their research work. Megan studied the properties of the solar wind and of the corona of the sun using VLA observations with NRAO scientist Tim Bastian. She will do graduate work at the University of Colorado at Boulder. Eric did research work in a variety of fields: with Prof Mark Whittle on Hubble data on a star-forming dwarf galaxy, and with Prof Shane Davis using a magneto-hydrodynamic code studying accretion disks around black holes. Eric spent last summer at the university of Zurich, Switzerland working on simulations of galaxy evolution. He will do graduate work at the University of Heidelberg. The prize consists of a certificate and an award of $1000.  Since this year it is shared, each recipient will receive $500.

Thankful Cromartie is awarded a NASA Einstein Fellowship

March 25, 2020

The NASA Hubble Fellowship Program (NHFP) supports outstanding postdoctoral scientists to pursue independent research which contributes to NASA Astrophysics, using theory, observation, experimentation, or instrumental development.  The NHFP preserves the legacy of NASA’s previous postdoctoral fellowship programs. Once selected, fellows are named to one of three sub-categories corresponding to NASA’s “big questions”: How Does the Universe Work? - Einstein Fellows; How Did We Get Here? - Hubble Fellows; Are We Alone? - Sagan Fellows.

Thankful Cromartie was born and raised in Chapel Hill, North Carolina, and received her BS with highest honors in physics from the University of North Carolina at Chapel Hill. She has pursued her PhD work as a graduate student in the University of Virginia's Department of Astronomy, where she currently works under the supervision of Dr. Scott Ransom as a National Radio Astronomy Observatory Grote Reber doctoral fellow. She will be defending her PhD in April 2020. 

Thankful's research focuses on using millisecond pulsar (MSP) timing to explore fundamental physics. She is a member of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration, whose goal is to detect low-frequency gravitational waves from supermassive black hole binaries with an array of precisely timed MSPs. As a graduate student, she has explored topics under the NANOGrav umbrella, including the discovery of new MSPs for inclusion in the array using the Arecibo and Green Bank radio telescopes. Thankful has also worked on constraining the poorly understood neutron star interior equation of state using pulsar-timing observations of relativistic Shapiro delay. As an Einstein fellow at Cornell, she will continue to work within NANOGrav, pursuing ambitious searches for MSPs and using the full extent of the NANOGrav dataset to further constrain the equation of state. She looks forward to conducting joint analyses of radio and Gamma/X-ray data to improve NANOGrav's sensitivity and further understand the behavior of matter at supranuclear densities.

Building a Cluster of Galaxies - the Shocking Truth!

December 20, 2019

A group of astronomers, including U.Va.'s Craig Sarazin, have observed two groups of galaxies slamming into one another at a speed of about 4 million miles per hour.  The colliding groups will eventually merge and form a single cluster of galaxies; these are the largest objects in the Universe.  Clusters contain as much material as one million, billion stars.  This cosmic train wreck was observed with a number of space and ground-based observatories, including by U.Va. astronomers using the Apache Point Observatory (APO) in New Mexico.  U.Va. is a member of APO.  The picture above shows a composite of the X-ray and optical images of the merging groups.  These observations were the subject of an image press release by NASA's Chandra X-ray Observatory, which contains much more information and many more images.  There is also a video about this collision on YouTube at https://youtu.be/PVFkc46CyYY.
