A Survey of hard spectrum ROSAT sources 1 : X – ray source catalogue
We present a catalogue of 147 serendipitous X–ray sources selected to have hard spectra (α < 0.5) from a survey of 188 ROSAT fields. Such sources must be the dominant contributors to the X-ray background at faint fluxes. We have used Monte Carlo simulations to verify that our technique is very efficient at selecting hard sources: the survey has ≥ 10 times as much effective area to hard sources ...
متن کاملThe ROSAT Bright Survey: I. Identification of an AGN sample with hard ROSAT X-ray spectra
The ROSAT Bright Survey (RBS) aims to completely optically identify the more than 2000 brightest sources detected in the ROSAT all-sky survey at galactic latitudes |b| > 30◦ (excluding LMC, SMC, Virgo cluster). This paper presents a subsample of 66 bright point-like ROSAT survey sources with almost hard PSPC spectra, the hardness ratio HR1 is > 0.5 for most of the sources. The subsample could b...
متن کاملA Survey of hard spectrum ROSAT sources 2: optical identification of hard sources
We have surveyed 188 ROSATPSPC fields for X–ray sources with hard spectra (α < 0.5); such sources must be major contributors to the X–ray background at faint fluxes. In this paper we present optical identifications for 62 of these sources: 28 AGN which show broad lines in their optical spectra (BLAGN), 13 narrow emission line galaxies (NELGs), 5 galaxies with no visible emission lines, 8 cluste...
متن کاملThe Hamburg/RASS Catalogue of optical identifications Northern high-galactic latitude ROSAT Bright Source Catalogue X-ray sources
We present the Hamburg/RASS Catalogue (HRC) of optical identifications of X-ray sources at highgalactic latitude. The HRC includes all X-ray sources from the ROSAT Bright Source Catalogue (RASS-BSC) with galactic latitude |b| ≥ 30◦ and declination δ ≥ 0◦. In this part of the sky covering∼10 000 deg the RASS-BSC contains 5341 X-ray sources. For the optical identification we used blue Schmidt pri...
متن کاملThe ROSAT Deep Survey I. X-ray sources in the Lockman Field
The ROSATDeep Survey in the LockmanHole is the most sensitive X-ray survey performed to date, encompassing an exposure time of 207 ksec with the PSPC and a total of 1.32 Msec with the HRI aboard ROSAT. Here we present the complete catalogue of 50 X-ray sources with PSPC fluxes (0.5-2 keV) above 5.5 × 10−15 erg cm−2 s−1. The optical identifications are discussed in an accompanying paper (Schmidt...
