Grzegorz M. Madejski

Lecturer
My English-speaking friends know me as Greg. I was born in Poland, but my college and graduate education was in the US, respectively at MIT and Harvard. After spending 14 years at NASA/Goddard, I arrived in Stanford in 2000. My research interests are mainly in extragalactic high-energy astrophysics. This includes (1) studies of active galactic nuclei, and an associated formation and evolution of relativistic jets; and (2) studies of clusters of galaxies, and in particular the processes responsible for the heating of the X-ray emitting intra-cluster gas. Besides taking advantage of data from the Fermi Gamma-ray Observatory, I am involved in analyzing and interpreting observations performed with X-ray satellites such as NuSTAR, a recently-launched NASA satellite, sensitive in the hard X-ray band, and Hitomi, a joint Japanese - US X-ray astronomy mission.

Research Projects

Fermi Gamma-ray Space Telescope

The Fermi Gamma-ray Space Telescope (FGST or Fermi) is a space-based observatory used to perform gamma-ray astronomy observations from low-Earth orbit.

Imaging X-ray Polarization Explorer

The Imaging X-ray Polarization Explorer (IXPE), scheduled to launch in 2021, will be the first satellite dedicated to measuring the polarization of X-rays emitted by astrophysical objects in the 1-10keV band.
