SUMMARY:Deciphering the Non-Thermal Universe with First Principles Mod
 eling of Plasma Turbulence\, Plasma Physics (Physics/ECE/NE 922) Semin
 ar\, Luca Comisso\, Columbia University
DESCRIPTION:Understanding the origin of non-thermal particles and radi
 ation that are commonly observed from a variety of astrophysical sourc
 es represents the most promising opportunity to uncover the physics of
  these astrophysical systems. In systems such as the Sun\, neutron sta
 rs\, black holes\, and astrophysical jets\, the dissipation of large r
 eservoirs of magnetic energy provides the most likely path toward part
 icle acceleration and copious radiative emission. In view of the enorm
 ous scale separation between the energy-carrying scale and the plasma 
 kinetic scales\, turbulence is a natural candidate for converting the 
 available magnetic energy into particle kinetic energy and radiation. 
 In this talk\, I will outline recent developments in our understanding
  of the physics underlying particle acceleration in turbulent plasmas\
 , including the role of magnetic reconnection and radiative losses. I 
 will also highlight the most important implications for understanding 
 the non-thermal emission from several high-energy astrophysical system
 s\, especially for Pulsar Wind Nebulae and Gamma-Ray Bursts. Lastly\, 
 I will briefly highlight the future prospects of this research program
 .
