The Chandra Deep Field North Survey. XIII. 2 Ms Point-Source Catalogs
We present point-source catalogs for the ?2 Ms exposure of the Chandra Deep Field North, currently the deepest X-ray observation of the universe in the 0.5?8.0 keV band. Five hundred and three (503)
X-Ray Imaging Spectrometer (XIS) on Board Suzaku
The XIS is an X-ray Imaging Spectrometer system, consisting of state-of-the-art charge-coupled devices (CCDs) optimized for X-ray detection, camera bodies, and control electronics. Four sets of XIS
Advanced CCD imaging spectrometer (ACIS) instrument on the Chandra X-ray Observatory
The ACIS instrument has been operating for three years in orbit, producing high quality scientific data on a wide variety of X-ray emitting astronomical objects. Except for a brief period at the very
The X-Ray Observatory Suzaku
High-sensitivity wide-band X-ray spectroscopy is the key feature of the Suzaku X-ray observatory, launched on 2005 July 10. This paper summarizes the spacecraft, in-orbit performance, operations, and
Diffuse X-Ray Emission in a Deep Chandra Image of the Galactic Center
We examine the spectrum of diffuse emission detected in the 17' ? 17' field around Sgr A* during 625 ks of Chandra observations. The spectrum exhibits He-like and H-like lines from Si, S, Ar, Ca, and
We present an exploratory Chandra ACIS-S3 study of the diffuse component of the cosmic X-ray background (CXB) in the 0.3–7 keV band for four directions at high Galactic latitudes, with emphasis on
The Evolution of Structure in X-ray Clusters of Galaxies
Using Chandra archival data, we quantify the evolution of cluster morphology with redshift. Clusters form and grow through mergers with other clusters and groups, and the amount of substructure in
Suzaku Observations of the Local and Distant Hot ISM
Suzaku observed the molecular cloud MBM 12 and a blank field less than 3 ◦ away to separate the local and distant components of the diffuse soft X-ray background. Towards MBM 12, a local (D 275pc) O
X-Ray Temperature and Mass Measurements to the Virial Radius of Abell 1413 with Suzaku
We present X-ray observations of the northern outskirts of the relaxed galaxy cluster A1413 with Suzaku, whose XIS instrument has the low intrinsic background needed to make measurements of these low
The Redshift Evolution of the 2-8 keV X-Ray Luminosity Function
The high angular resolution and sensitivity of the Chandra X-Ray Observatory has yielded large numbers of faint X-ray sources with measured redshifts in the soft-energy (0.5-2 keV) and hard-energy
