Applications are invited for two Postdoctoral positions in observational and theoretical black hole
astrophysics at the Department of Astronomy/Steward Observatory, the University of Arizona.
The Department of Astronomy/Steward Observatory is a vibrant hub of technological innovations in
both observational and theoretical astrophysics. With over 80 faculty members, new instruments, data
processing methods, theoretical models, and numerical algorithms are constantly being developed. The
successful applicants will be able to conduct independent research and to collaborate with Profs. Dan
Marrone, Remo Tilanus, and Chi-kwan Chan, and Dr. Amy Lowitz, among others, on some of our
upcoming projects:

- Instrumentation development for the Event Horizon Telescope, a global array of millimeter-wavelength
radio observatories studying event-horizon-scale physics through the technique of VLBI.
- Analysis and interpretation of Event Horizon Telescope data, particularly for the key targets: the Sgr A*
black hole in the Milky Way galaxy and the M87* black hole.
- Designing and implementing space-borne VLBI stations to extend the reach of horizon-scale VLBI.
- Developing new theoretical and numerical models of supermassive black holes using GPU and FPGAaccelerated
GRMHD and GRRT codes.
- Architecting and deploying cutting-edge cyber-infrastructure to enable computation- and dataintensive
astrophysics.

The successful applicants will also have access to the observational and computational facilities of the
Department of Astronomy/Steward Observatory, including the 10-meter Submillimeter Telescope on
Mt. Graham, the 12-meter ALMA Prototype Antenna on Kitt Peak, the 2×8.4m Large Binocular
Telescope, the 6.5m MMT, the twin 6.5m Magellan telescopes, and over 2,000,000 core-hours per year
on the Puma and Ocelote Supercomputers from the University of Arizona. These are two-year positions
with possible extension.

Candidates should have a Ph.D. in Astronomy/Physics or related fields, or expect to complete their Ph.D.
by the end of the summer of 2022, and have a strong background relevant to one or more of the topical
areas described above.
Preferred qualifications:
Experience in one or more of the following topics: millimeter-wavelength instrumentation, radio
interferometric observations (especially with ALMA or VLBI), and theoretical and numerical modeling of black holes.
