[60.25] Gone With The Galactic Wind: Observation and Theory

Z. Li, D. Wang (Univ. of Mass.)

The study of X-ray emitting diffuse gas in galactic halos is of importance in understanding the formation and evolution of galaxies. A spherical steady galactic wind model is developed and confronted with the Chandra observation of the bulge-dominated edge-on Sa galaxy M104. We derive super-solar abundances for Fe-like elements from spectral fit, which is consistent with ISM enrichment predominated by Type Ia supernovae in the galactic bulge.
