NED Abstract

Copyright by Royal Astronomical Society. 1999MNRAS.310...30C X-ray observations of low-power radio galaxies from the B2 catalogue C. M. Canosa, D. M. Worrall, M. J. Hardcastle and and M. Birkinshaw Accepted 1999 June 25. Received 1999 June 25; in original form 1999 April 7 ABSTRACT We present an analysis of X-ray data, taken with ROSAT, for a well-defined sample of low-power radio galaxies from the Bologna B2 catalogue. Where possible, the HRI has been used in order to take advantage of the high spatial resolution provided by this instrument. A variety of models are fitted to radial profiles in order to separate the resolved and unresolved X-ray emission from the galaxies. We demonstrate a strong, approximately linear, correlation between the luminosities of the unresolved X-ray components and the 5-GHz luminosities of the radio cores in this sample. This suggests a physical relationship between the soft X-ray emission of radio galaxies and the jet-generated radio core emission. We infer a nuclear jet-related origin for at least some of the X-ray emission. Keywords: galaxies: active - galaxies: cluster:general - X-rays: galaxies
