The Subaru/XMM-Newton Deep Survey (SXDS). III. X-Ray Data
Simpson, Chris; Ueda, Yoshihiro; Carrera, Francisco J. +10 more
We present the X-ray source catalog in the Subaru/XMM-Newton deep survey. A continuous area of 1.14 deg2 centered at R .A . = 02h18m and decl . = - 05° is mapped by seven pointings with XMM-Newton covering the 0.2-10 keV band. From the combined images of the EPIC pn and MOS cameras, we detect 866, 1114, 645, and 13…
The Long-Term Variability of the X-Ray Sources in NGC 6946 and NGC 4485/4490
Kong, Albert K. H.; Homan, Jeroen; Fridriksson, Joel K. +2 more
We analyze data from five Chandra observations of the spiral galaxy NGC 6946 and from three Chandra observations of the irregular/spiral interacting galaxy pair NGC 4485/4490, with an emphasis on investigating the long-term variability exhibited by the source populations. We detect 90 point sources coincident with NGC 6946 down to luminosities of …
The ChaMP Extended Stellar Survey (ChESS): Photometric and Spectroscopic Properties of Serendipitously Detected Stellar X-Ray Sources
Silverman, J. D.; Covey, K. R.; Barkhouse, W. A. +9 more
We present 348 X-ray-emitting stars identified from correlating the Extended Chandra Multiwavelength Project (ChaMP), a wide-area serendipitous survey based on archival X-ray images, with the Sloan Digital Sky Survey (SDSS). We use morphological star/galaxy separation, matching to an SDSS quasar catalog, an optical color-magnitude cut, and X-ray d…
