  title = {Magnetic Reconnection under Extreme Astrophysical Plasma Conditions},
  abstract = {Magnetic reconnection is a key fundamental plasma-physical process operating in many astrophysical systems and responsible for sudden and often violent release of accumulated magnetic energy, powering spectacular X-ray and gamma-ray flares. In many of the most enigmatic relativistic high-energy astrophysical systems (those associated with neutron stars and black holes) the plasma conditions are so extreme that exotic physics effects -- e.g., strong interaction of plasma with radiation and QED processes such as pair creation -- need to be included self-consistently in the plasma description. These effects modify reconnection dynamics, energetics, nonthermal particle acceleration, and observable radiative signatures. They thus necessitate the exploration of a new frontier in plasma astrophysics -- radiative magnetic reconnection. In this talk I will present a systematic overview of extreme radiative magnetic reconnection, with a focus on an orderly classification of the different physical parameter regimes. I will also discuss astrophysical applications of radiative reconnection with concrete examples drawn from modern high-energy astrophysics research.In collaboration with: John Mehlhaff, University of Colorado, Boulder; Gregory Werner, University of Colorado, Boulder; Mitchell Begelman, JILA and University of Colorado, Boulder
