Radio jets and diffuse X - ray emission around the peculiar galaxy pair ESO 295 - IG 022
We report Australia Telescope Compact Array (ATCA) radio-continuum and ROSAT PSPC X-ray observations of the region surrounding the peculiar galaxy pair ESO 295-IG022, lying at the centre of the poor cluster Abell S0102. We identify a radio galaxy coincident with the galaxy pair, with bipolar, bent radio jets appearing centred on the southern galaxy, and extending both to the south, for about 95...
متن کاملChandra Study of an Overdensity of X-ray Sources around Two Distant (z∼0.5) Clusters
We present results from a Chandra X-ray Observatory study of the field X-ray source populations in 4 different observations: two high-redshift (z∼0.5) clusters of galaxies 3C295 and RXJ003033.2+261819; and two non-cluster fields with similar exposure time. Surprisingly, the 0.5-2 keV source surface densities (∼ 900-1200 sources deg at a flux limit of 1.5× 10 erg cms) measured in an ∼8×8 area su...
متن کاملGlobular cluster x-ray sources.
Globular clusters and x-ray astronomy have a long and fruitful history. Uhuru and OSO-7 revealed highly luminous (> 10(36) ergs(-1)) x-ray sources in globular clusters, and Einstein and ROSAT revealed a larger population of low-luminosity (< 10(33) ergs(-1)) x-ray sources. It was realized early on that the high-luminosity sources were low-mass x-ray binaries in outburst and that they were order...
متن کاملX-ray and lensing results on the cluster around the powerful radio galaxy 4C+55.16
We present results from ASCA and ROSAT HRI observations of the powerful radio galaxy 4C+55.16 at redshift 0.24. Extended soft X-ray emission is imaged by the ROSAT HRI. The X-ray brightness profile is sharply peaked on the radio galaxy, characteristic of a strong cooling flow. The X-ray spectrum obtained from ASCA is consistent with multi-phase intracluster gas. There is evidence for an absorbe...
