A Chandra ACIS-S imaging observation of the nearby galaxy M81 (NGC 3031) reveals nine luminous soft X-ray sources. The local environments, X-ray spectral properties, and X-ray light curves of the sources are presented and discussed in the context of prevailing physical models for supersoft sources. It is shown that the sample falls within expectations based on population synthesis models taken from the literature, although the high observed luminosities (Lobs � 2 � 10 36 –3 � 10 38 ergs s � 1…

CHANDRA X-RAY OBSERVATIONS OF THE SPIRAL GALAXY M81
• Physics
• 2003
A Chandra X-Ray Observatory ACIS-S imaging observation is used to study the population of X-ray sources in the nearby Sab galaxy M81 (NGC 3031). A total of 177 sources are detected with 124 located
An XMM–Newton view of M101 – I. The luminous X-ray source population
• Physics
• 2003
No definitive spectral signatures are found to indicate that these sources contain neutron star primaries, and it is concluded that they are likely to be stellar-mass black hole XRBs (BHXBs), with black hole masses of ∼2- 23 Mif accreting at the Eddington limit.
Luminous Supersoft X-Ray Sources in External Galaxies
• Physics
• 2003
We use a set of conservative criteria to identify luminous supersoft X-ray sources (SSSs) in external galaxies. We test this approach on blackbody models and then apply it to Chandra data from four

No Periodicity Revealed for an “Eclipsing” Ultraluminous Supersoft X-Ray Source in M81
Luminous supersoft X-ray sources found in the Milky Way and Magellanic Clouds are likely white dwarfs that steadily or cyclically burn accreted matter on their surface, which are promising Type Ia
Properties of discrete X-ray sources in the starburst spiral galaxy M 83
We have identified 127 discrete sources in a Chandra ACIS observation of M83, with a detection limit of approximate to3 x 10(36) erg s(-1) in the 0.3-8.0 keV band. We discuss the individual X-ray
