SUMMARY:Extreme Plasmas around Black Holes and Neutron Stars\, Plasma 
 Physics (Physics/ECE/NE 922) Seminar\, Sasha Philippov\, University of
  Maryland and SCEECS
DESCRIPTION:Astrophysical compact objects\, such as neutron stars and 
 black holes\, are powerful sources of non-thermal electromagnetic emis
 sion spanning many orders of magnitude in photon energy\, from radio w
 aves to multi-TeV gamma-rays\, and\, potentially\, of high-energy neut
 rinos and cosmic rays. Despite multiple groundbreaking observational d
 iscoveries done in recent years\, our understanding of the dynamics of
  relativistic plasmas that produce these multi-messenger signatures re
 mains limited. In this talk\, I will describe the activities of the re
 cently started Simons Collaboration on Extreme Electrodynamics of Comp
 act Sources (SCEECS) aiming at producing first-principles descriptions
  of relativistic and radiative plasmas near compact objects. I will sh
 ow a few examples of modeling the observed light coming from these rem
 arkable astrophysical laboratories using numerical simulations.
