We are deeply saddened by the passing of our colleague, Professor Alexei Khokhlov, on May 4, 2019. Professor Khokhlov joined our department in 2003, playing a large role in the Flash Center for Computational Science, and he was also a member of the Enrico Fermi Institute. He was a world leader in theoretical and computational astrophysics and reactive flow fluid dynamics. His main research focus was large-scale multi-dimensional numerical simulations of thermonuclear Type Ia supernova explosions. He will be deeply missed by his colleagues, family, and friends.

His obituary can be read here: Alexei M. Khokhlov, theoretical and computational astrophysicist, 1954-2019.

The family asks that in lieu of flowers, to please consider making a donation in memory of Alexei Khokhlov to the Baltimore Hope Lodge run by the Cancer Society.

April 8, 2019
Fakhri Zahedy has received a prestigious Carnegie Postdoctoral fellowship to start in the fall of 2019. The position is for three years.

The Carnegie Fellowship is intended to encourage long-term research in observational or theoretical astrophysics and/or instrumentation. The fellowships are extremely competitive, and are prized for their independence and for the resources they afford the fellows. Each fellow is key to ehnancing the Carnegie mission and expanding Carnegie's influence of unfettered, imaginative scientific research into the next generations.

Vadim Semenov was selected for the prestigious NASA Hubble Fellowship Program (NHFP)
April 8, 2019
Vadim will be taking Hubble fellowship to the Institute for Theory and Computation (ITC) at Harvard. After 3 years of the Hubble fellowship he will continue there as an ITC fellow, position he was also offered as part of the process.

The program enables outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using theory, observation, experimentation, or instrument development. Each fellowship provides the awardee up to three years of support.

Donald York has been awarded the Royal Astronomical Society Service Award for Astronomy
January 13, 2019
Prof. Donald G. York
Dear Colleagues,

Please join me in congratulating Don York who has been awarded the Royal Astronomical Society Service Award for Astronomy.

The RAS citation reads:
"Professor Donald York, as the Founding Director of the Sloan Digital Sky Survey (SDSS), was a key figure in the conception, design, construction, and initial operation of one of the most successful astronomical facilities of the 21st century. With its first-ever digital image of the entire northern high galactic latitude sky, homogeneously and painstakingly calibrated in a novel photometric system, plus millions of homogeneously obtained spectra, SDSS has touched every subfield of astronomy.

Multiple studies agree that SDSS is the most cited and most impactful facility in ground-based astronomy, or even all astronomy. More than 7,600 papers refer to SDSS in the title or abstract, and these publications have garnered roughly 400,000 citations. Twenty-five of these papers have 1,000 or more citations, and almost 800 have 100 or more citations.

Professor York enabled one of the most significant astronomical projects of our lifetimes, one that benefits the entire international community, and is a truly deserving recipient of the RAS Service Award."

Congratulations Don!

John Carlstrom,
Subramanyan Chandrasekhar Distinguished Service Professor and Chair Department of Astronomy & Astrophysics

"Citizen Scientists Find New World with NASA Telescope", JPL News
Using data from NASA's Kepler space telescope, citizen scientists have discovered a planet roughly twice the size of Earth located within its star's habitable zone, the range of orbital distances where liquid water may exist on the planet's surface. The new world, known as K2-288Bb, could be rocky or could be a gas-rich planet similar to Neptune. Its size is rare among exoplanets - planets beyond our solar system.

"It's a very exciting discovery due to how it was found, its temperate orbit and because planets of this size seem to be relatively uncommon," said Adina Feinstein, a University of Chicago graduate student who discussed the discovery on Monday, Jan. 7, at the 233rd meeting of the American Astronomical Society in Seattle. She is also the lead author of a paper describing the new planet accepted for publication by The Astronomical Journal.

Nancy Grace Roman, "mother" of the Hubble Telescope, dies aged 93
January 2, 2019

Dear Colleagues,

I am sad to inform you that Nancy Grace Roman died on Christmas Day at the age of 93.

She received her PhD in Astronomy and Astrophysics at UChicago in in 1949. Dr. Roman stayed on as a postdoc, instructor, and then joined the faculty as an assistant professor, becoming the first woman on the department's faculty. Not believing the university would tenure her, she left for a position with the Naval Research Laboratory in Washington, DC and was then recruited to the newly established NASA, where she served as the Chief of the Astronomy and Relativity Programs in the NASA Office of Space Science.

Dr. Roman had enormous impact on Astronomy and Astrophysics. She is particularly well known for her role in planning the Hubble Space Telescope and is often referred to as the "Mother of Hubble". Dr. Roman was also a strong advocate for women in the sciences.

As many of you know, the A&A department has decided to name the seminar and instruction room ERC 583 after Nancy Grace Roman to recognize her outstanding scientific career, her extraordinary leadership at NASA, and her decades of work as an advocate for inclusion in science. In her reply to our request to name the room after her, she said she was honored and included, "I hope that naming a room for a woman will encourage your female students. Astronomy needs more diversity."

The plans for renovating ERC 583 are proceeding, including her image on the glass wall and several improvements to the room.

You can learn more about Nancy Grace Roman's life in an article she wrote for ASP "Nancy Roman: An Astronomer's Life" and in a recent UChicago Magazine article "A wider scope".

Sincerely,
John Carlstrom
Chair and Subramanyan Chandrasekhar Distinguished Service Professor
