Abstract (from CDS):

We have detected diffuse soft X-ray emission (0.4-1 keV) from the disk of the spiral galaxy NGC 2403 with Chandra. This diffuse emission [with a total luminosity of 2.1x1038 ergs.s–1 and a gas temperature of (2-8)x106 K] is well separated from the numerous bright point sources. NGC 2403 is a luminous spiral galaxy with a high rate of star formation. Recent H I observations have revealed an extended H I halo with anomalous velocities and a general inflow toward the central regions of the galaxy. This result and the present detection of a diffuse, hot X-ray-emitting gas point to a very active disk-halo connection and galactic fountain types of phenomena.
