A Multiwavelength Exploration of the Grand Design Spiral M83: The X-ray Point Source Population
Abstract
We have obtained a series of deep X-ray images of the nearby galaxy M83, with a total exposure 729 ksec with Chandra. There are approximately 360 point sources detected with high confidence, with large concentrations in the nuclear region and along the sprial arms. The detected sources include about 60 sources whose positions are coincident with supernovae or supernova remnants candidates in M83, including one extremely hard source associated with SN1957d. Of the X-ray sources, 22 of these were detected in a new radio survey of M83 obtained with ATCA. Half of these are coincident with X-ray-detected SNRs. Here we describe our on-going effort to classify the point source population through a combination of spectral and temporal analysis, to eliminate background AGN and foreground stars from the sample, and to associate M83 sources with other morphological features, such as young stellar clusters, in the galaxy. The derived luminosity function for M83 X-ray sources will be presented.
