Grzegorz M. Madejski
Lecturer
BioMy 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.

Raghu Mahajan
Visiting Assistant Professor
Current Research and Scholarly InterestsMy research interests are wide-ranging:
1) In the context of gravity, how does spacetime emerge from its dual quantum system? How does the dual quantum system encode the answers to questions that involve local physics in semi-classical gravity? How do you avoid the "firewall" paradox in the context of black-hole evaporation?
2) How do you calculate electrical and heat currents in strongly-coupled many-body systems? How do you explain the linear-in-temperature resistivity in high-temperature cuprates?
3) Use tensor network methods to study electrical and heat transport and also the real-time dynamics of systems out of thermal equilibrium.
