Ilse Cleeves, astronomy, University of Virginia, is among 24 outstanding teacher-scholars in chemistry, physics, and astronomy named recipients of Research Corporation for Science Advancement’s 2022 Cottrell Scholar Awards. Each award is $100,000.
Recipients are chosen through a rigorous peer-review process of applications from a wide variety of public and private research universities and primarily undergraduate institutions in the United States and Canada. Their award proposals incorporate both research and science education.
Research Corporation for Science Advancement, founded in 1912, is a private foundation that funds early stage, high-potential basic research in the physical sciences (astronomy, chemistry, physics, and related fields) at colleges and universities in the United States and Canada.
It is with incredible sadness that we announce the passing of Professor John Hawley after a long fight with cancer. In addition to being a brilliant scientist and dedicated advocate for the Astronomy Department and UVA as a whole, John was a valued mentor and colleague, and his sharp wit will be missed.
John received his Ph.D. in Astronomy from the University of Illinois at Urbana–Champaign in 1984. After a Bantrell Prize Fellowship in Theoretical Astrophysics at CalTech, he was hired at UVA in the Astronomy Department in 1987. His 15 years of leadership here were comprised of Department Chair for two terms, Associate Dean for the Sciences for two terms, and as AD for Academic Affairs and Senior AD for Academic Affairs these last two years.
John's primary research interest was the physics of gas accretion. While accretion is ubiquitous in the universe, the physical mechanism that drives it was not well understood. In our daily lives, when water comes out of a tap, it spirals inward and goes down the drain due to friction with the walls of the sink. The equivalent source of friction for accretion was assumed to be turbulence in the gas flow, but the origin of that turbulence was a mystery for almost two decades. In the 1990’s, working with Steven Balbus, John identified a powerful instability in magnetized gases that drives the turbulent flow, allowing a detailed understanding of the accretion process. Today, the “magnetorotational instability” is applied to study a wide variety of celestial objects, from accretion disks around black holes to the disks from which stars and planets form.
John’s research accomplishments were widely recognized. He was the 1993 recipient of the Helen B. Warner Prize for Astronomy of the American Astronomical Society. He and Steve Balbus shared the 2013 Shaw Prize in Astronomy for their discovery, which included a US $1 million cash award. He was awarded the Hamilton Chair in Astronomy in 2014.
John also contributed fundamental insights in computational astrophysics. With the recognition that many fluid dynamics processes are too complicated to understand with pencil and paper calculations, he was a leader in developing numerical algorithms to solve for the evolution of magnetized fluids, allowing a detailed study of their behavior. With these computational tools, he and his collaborators were able to study disk accretion of gas, the formation of jets, the efficiency of disks in emitting radiation, as well as the effects of general relativity on the gas flow. As an expert in high-performance computing, he advocated for the Rivanna computer cluster which now serves the large-scale computing needs of many UVA researchers.
John’s sense of humor was legendary. Whether it was at faculty meetings, or the Kovalenko dinner speeches, or even the Chairs and Director’s meetings for the College, you always knew he could find something funny even in the driest topics and most arcane details. He will be sorely missed. We wish his wife, Katherine Holcomb, and all his family comfort at this challenging time.

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.

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.

Professor Ilse Cleeves has recieved the Research Excellence Award by the University of Virginia Research Achievement Awards committee. Each year up to three researchers are selected across UVA for this honor through a nomination process and a rigorous review by a multi-disciplinary awards committee. This award recognizes faculty members who have generated sufficient volume of scholarship of high quality and are emerging in their fields as leaders and acknowledged as such by their peers. Chair Craig Sarazin says, "Ilse has won almost every award available in the world of Astronomy. It is not at all a surprise that U.Va. would recognize the quality of her research."
By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes – that could be the first radio emission collected from a planet beyond our solar system.
The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de Paris - Paris Sciences et Lettres University and Jean-Mathias Griessmeier of the Université d’Orléans will publish their findings in the forthcoming research section of Astronomy & Astrophysics, on Dec. 16.
Nitya Kallivayalil’s research was featured in a Quanta magazine article entitled “The New History of the Milky Way”, which explores the outsize influence of the Large Magellanic Cloud on our own galaxy.

During the virtual Astronomy Department Diploma ceremony on 17 May, the winners of the Lawrence W. Fredrick award of the Astronomy department and the winners of three undergraduate Astronomy awards were announced.
Lawrence W. Fredrick Award
This award recognizes one or two outstanding astronomy graduate teaching assistants (TA) in the preceding year. The award is named for the Chair of the Astronomy Department in the 1960's and 1970's. This year's award goes jointly to Luca Beale and Daniel Lin. Luca was cited for his work as head TA, his role in the graduate mentoring of undergraduate majors and his work in organising the Bob Rood Graduate symposium. Daniel was cited by for his outstanding TA work, going above and beyond the call of duty in his efforts to help and educate undergraduate students. The award includes a monetary prize and a certificate.
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.
