Abstract

Emission from discrete point sources dominates the X-ray luminosity in spiral galaxies. We present results from a survey of 11 nearby, nearly face-on spiral galaxies with the Chandra X-ray Observatory. These galaxies span the Hubble sequence for spirals, allowing insights into the X-ray source population of many diverse systems. In this paper, we present source lists for the 11 galaxies along with fluxes, luminosities, X-ray colors, and variability properties. We briefly discuss X-ray luminosity functions and how they relate to star formation of the host galaxies. We also discuss source colors and variability and what these can tell us about the composition of the X-ray source population.
