Identification of soft high galactic latitude RASS X-ray sources
We present a summary of spectroscopic identifications of bright soft high galactic latitude X-ray sources from the ROSAT All-Sky Survey with total PSPC count rates 0.11 < CR < 0.5 cts s−1 and hardness ratios HR1 < 0. This study supplements the identification program of a complete sample of sources withCR ≥ 0.5 cts s−1 presented previously. Spectroscopic identifications are presented for 70 of 7...
متن کاملSynchrotron Polarization at High Galactic Latitude
We present preliminary results from mapping the high-latitude Galactic polarization with the Effelsberg Telescope at λ21 cm. Structures on the resulting maps are mostly on the scale of several degrees. The results show detection of polarization over most of the field, at the level of tens of percent of the synchrotron emission. The evidence of more structure in Stokes Q and U rather than in √ Q...
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 Galactic contribution to high latitude diffuse γ-ray emission
Recent evidence for a large Galactic halo, based on cosmic-ray radioactive nuclei, implies a significant contribution from inverse Compton emission at high Galactic latitudes. We present predictions for the expected intensity distribution, and show that the EGRET gamma-ray latitude distribution is well reproduced from the plane to the poles. We show that the Galactic component at high latitudes...
متن کاملDiscovery of an Isolated Compact Object at High Galactic Latitude
We report discovery of Calvera, a compact object at high Galactic latitude. We initially identified Calvera as a ROSAT All-Sky Survey Bright Source Catalog X-ray source, 1RXS J141256.0+792204, statistically likely to possess a high X-ray to optical flux ratio. Further observations using Swift, GeminiNorth, and the Chandra X-ray Observatory refined the source position and confirmed the absence o...
