Division D High Energy Phenomena and Fundamental Physics

Scientific Objectives

Division D subsumes the old Div. XI (Space and High Energy Astrophysics) with a broader scientific perspective including, e.g., "multi-messenger astronomy" (cosmic rays, neutrinos, gravitational waves, etc.), and non-thermal phenomena emitting radiation from the radio to TeV gamma-rays. Interests span from the mildly-relativistic electrons of supernova remnants or the hot intracluster medium, to ultra-relativistic cosmic-rays and their products in active galaxies and elsewhere. Phenomena include plasma astrophysics, magnetohydrodynamics, shocks, particle acceleration, photoionization, jets, outflows, bursts, extreme gravity, strong magnetic fields, etc. Example questions of topical interest might include the physics of dark matter, active-galaxy feedback, missing baryons in the warm/hot phase of the intergalactic medium, and the equation of state of neutron-star matter. Some of these topics will be shared with Div.J ("Galaxies & Cosmology").
