The Chandra Source Catalog Release 2 Series
Ian N. Evans, Janet D. Evans, J. Rafael Martínez-Galarza +17
The Chandra Source Catalog (CSC) is a virtual X-ray astrophysics facility that enables both detailed individual source studies and statistical studies of large samples of X-ray sou…
XMM-Newton and Chandra observations of the M31 globular cluster black hole candidate XB135: a heavyweight contender cut down to size
R. Barnard, F. Primini, M. R. Garcia +2
CXOM31 J004252.030+413107.87 is one of the brightest X-ray sources within the D_25 region of M31, and associated with a globular cluster (GC) known as B135; we therefore call this…
Determining X-Ray Source Intensity and Confidence Bounds in Crowded Fields
F. A. Primini, V. L. Kashyap
We present a rigorous description of the general problem of aperture photometry in high energy astrophysics photon-count images, in which the statistical noise model is Poisson, no…
50 M31 black hole candidates identified by Chandra and XMM-Newton
R. Barnard, M. R. Garcia, F. Primini +1
Over the last ~5 years we have identified ~35 black hole candidates (BHCs) in M31 from their X-ray spectra. Our BHCs exhibited 0.3--10 keV spectra consistent with the X-ray binary…
Discovery of a new black hole transient within 100" (400 pc) of M31*
R. Barnard, M. R. Garcia, F. Primini +1
We identified a new X-ray transient CXOM31 004252.457+411631.17 (T13) in M31 during a 2013 June Chandra observation. This system is particularly exciting because it is located with…
Around 200 new X-ray binary IDs from 13 years of Chandra observations of the M31 center
R. Barnard, M. R. Garcia, F. Primini +3
We have created 0.3--10 keV, 13 year, unabsorbed luminosity lightcurves for 528 X-ray sources in the central 20' of M31. We have 174 Chandra observations spaced at ~1 month interva…
