Dimitrios Psaltis

Professor of Astronomy and Physics


My group has pioneered the development of tests of Einstein’s General Theory of Relativity using observations of black holes and neutron stars in the electromagnetic spectrum.

Research Group

I enjoy collaborating closely with graduate students, undergraduate students, and postdocs in my research group and from around the world.


I am the Project Scientist of the Event Horizon Telescope project, which aims to take the first pictures of the horizons of astrophysical black holes. I am also a member of various science working groups assisting in the utilization of data from space missions such as NICER.

I am a professor of Astronomy and Physics at theĀ University of Arizona. My research focuses on testing the theory of general relativity in the strong-field regime. I also work on various aspects of the physics and astrophysics of neutron stars and black holes, as well as on the properties of magnetohydrodynamic turbulence.

I am the Project Scientist of the Event Horizon Telescope, an international mm-VLBI experiment that aims to take the first picture of a black hole with horizon-scale resolution.

I also serve as the Chair of theĀ Theoretical Astrophysics Program at the University of Arizona. This interdisciplinary program facilitates theoretical astrophysics research among faculty, staff, and students in three departments (Astronomy, Physics, Lunar & Planetary Laboratory) at the University.
