AAS 198th Meeting, June 2001 Session 8.
Spiral galaxies are complex X-ray sources.
There is evidence for diffuse emission from hot gas, but it is a multitude of discrete sources which dominate the total flux. It was observed twice with Chandra, in Jan and Feb 2000. Finally, we show that there is no evidence for dramatic variations of the X-ray hardness ratio as a function of distance from the nucleus, perhaps suggesting that the binary production rate is in steady state in this disk galaxy.
