Title: DIFFUSE X-RAY EMISSION FROM NEARBY SPIRAL GALAXIES
Observer: Sanders
Subject Category: Normal Galaxies
Seq: 600107 ObsId: 00804
Long-term Plan bin: 30-Dec-1999
ABSTRACT
Our primary goal is to characterize the spatial distribution and spectral characteristics of the hot interstellar plasma in spiral galaxies. Since it is difficult to see soft X-rays coming from distances > ~ 100 pc from the Sun in the disk of our Galaxy, we propose to observe the hot interstellar plasma in several nearby face-on spiral galaxies. The hot phase of the interstellar medium of normal spiral galaxies is not well characterized or understood, but if the local filling fraction is representative of the Galactic value, its role is fundamental in the evolution of the interstellar medium. A secondary goal is to constrain the cosmological extragalactic diffuse background below 0.5 keV by quantifying its absorption by these intervening galaxies.
