The Chandra Deep Field-South Survey: 7 Ms Source Catalogs
Smail, I.; Hornschemeier, A. E.; Alexander, D. M. +23 more
We present X-ray source catalogs for the ≈7 Ms exposure of the Chandra Deep Field-South (CDF-S), which covers a total area of 484.2 arcmin2. Utilizing WAVDETECT for initial source detection and ACIS Extract for photometric extraction and significance assessment, we create a main source catalog containing 1008 sources that are detected i…
BAT AGN Spectroscopic Survey. V. X-Ray Properties of the Swift/BAT 70-month AGN Catalog
Treister, E.; Bauer, F. E.; Paltani, S. +18 more
Hard X-ray (≥10 keV) observations of active galactic nuclei (AGNs) can shed light on some of the most obscured episodes of accretion onto supermassive black holes. The 70-month Swift/BAT all-sky survey, which probes the 14-195 keV energy range, has currently detected 838 AGNs. We report here on the broadband X-ray (0.3-150 keV) characteristics of …
The Circum-Galactic Medium of Massive Spirals. II. Probing the Nature of Hot Gaseous Halo around the Most Massive Isolated Spiral Galaxies
Bregman, Joel N.; Anderson, Michael E.; Crain, Robert A. +3 more
We present the analysis of the XMM-Newton data of the Circum-Galactic Medium of MASsive Spirals (CGM-MASS) sample of six extremely massive spiral galaxies in the local universe. All the CGM-MASS galaxies have diffuse X-ray emission from hot gas detected above the background extending ∼ (30{--}100) {kpc} from the galactic center. This doubles the e…
An Optical and Infrared Photometric Study of the Young Open Cluster IC 1805 in the Giant H II Region W4 †
Lim, Beomdu; Park, Byeong-Gon; Nazé, Y. +7 more
We present deep wide-field optical CCD photometry and mid-infrared Spitzer/IRAC and MIPS 24 µm data for about 100,000 stars in the young open cluster IC 1805. The members of IC 1805 were selected from their location in the various color-color and color-magnitude diagrams, and the presence of Hα emission, mid-infrared excess emission, and X-r…
Galactic Sources Detected in the NuSTAR Serendipitous Survey
Hailey, Charles J.; Mori, Kaya; Aird, James +13 more
The Nuclear Spectroscopic Telescope Array (NuSTAR) provides an improvement in sensitivity at energies above 10 keV by two orders of magnitude over non-focusing satellites, making it possible to probe deeper into the Galaxy and universe. Lansbury and collaborators recently completed a catalog of 497 sources serendipitously detected in the 3-24 keV …
