The Chandra Multi - wavelength Project ( ChaMP ) : a serendipitous survey with Chandra archival data
The Chandra Multi-wavelength Project (ChaMP): a serendipitous survey with Chandra archival data. Abstract. The launch of the Chandra X-ray Observatory in July 1999 opened a new era in X-ray astronomy. Its unprecedented, < 0.5 " spatial resolution and low background are providing views of the X-ray sky 10-100 times fainter than previously possible. We have initiated a serendipitous survey (ChaMP...
متن کاملMulti - wavelength observations of serendipitous Chandra X - ray sources in the field of A 2390
We present optical spectra and near-infrared imaging of a sample of serendipitous X-ray sources detected in the field of Chandra observations of the A 2390 cluster of galaxies. The sources have 0.5-7 keV fluxes of 0.6 − 8 × 10 −14 erg cm −2 s −1 and lie around the break in the 2-10 keV source counts. They therefore are typical of sources dominating the X-ray Background in that band. Twelve of t...
متن کاملHard X-ray Emitting Active Galactic Nuclei Selected by the Chandra Multi-wavelength Project
We present X-ray and optical analysis of 188 AGN identified from 497 hard X-ray (f2.0−8.0keV > 2.7×10 erg cm s ) sources in 20 Chandra fields (1.5 deg) forming part of the Chandra Multiwavelength Project. These medium depth X-ray observations enable us to detect a representative subset of those sources responsible for the bulk of the 2–8 keV Cosmic X-ray Background. Brighter than our optical sp...
متن کاملMagpis: a Multi-array Galactic Plane Imaging Survey
We present the Multi-Array Galactic Plane Imaging Survey (MAGPIS), which maps portions of the first Galactic quadrant with an angular resolution, sensitivity and dynamic range that surpasses existing radio images of the Milky Way by more than an order of magnitude. The source detection threshold at 20 cm is in the range 1-2 mJy over the 85% of the survey region (5 < l < 32, |b|< 0.8) not covere...
متن کاملSpectral Analysis of the Chandra Comet Survey
Aims. We present results of the analysis of cometary X-ray spectra with an extended version of our charge exchange emission model (Bodewits et al. 2006). We have applied this model to the sample of 8 comets thus far observed with the Chandra X-ray observatory and spectrometer in the 300–1000 eV range. The surveyed comets are C/1999 S4 (), C/1999 T1 (McNaught– Hartley), C/2000 WM1 (...
