The Spectroscopy of Plasma Evolution from Astrophysical Radiation (SPEAR)

Jerry Edelstein, University of California at Berkeley

Trace the balance and flow of energy through the hot interstellar medium.

• A diffuse, far-ultraviolet (FUV) spectrometer to fly on the Korean KAISTSAT-4 mission.

• Measure the structure, mixing, and cooling of this hot IS plasma in our Galaxy, allowing us to test multi-phase models of the ISM, to examine hot gas interaction in superbubbles, to understand shock interactions between supernovae and the ISM, and to understand plasma phenomena found in galactic fountains and halos, active galaxies, galactic clusters, and possibly the intergalactic medium.
