[116.19] Chandra ACIS Spectra of the Hot Diffuse Component of Face-on Spiral Galaxies

E. M. Schlegel (Smithsonian Astrophysical Observatory), T. G. Pannuti (SIRTF Science Center/JPL/Caltech)

We present Chandra ACIS spectra of the hot diffuse component from observations of face-on spiral galaxies. Emission from point sources has been removed prior to extraction of the spectra. Corrections to the spectra are made for the time-dependent gain and the increasing absorption on the ACIS window. The source+background spectra were fit with MeKaL models for the source with a separate model describing the background. We report on the diffuse luminosity as a function of galaxy luminosity as well as other galaxy properties.

This research was supported by CXC grant no. AR3-4007A to SAO and NASA grant NAS8-39073 to the CXC.
