X-ray observations of five galaxy-quasar associations.
Five examples of close associations of quasars with bright, low redshiftgalaxies have been observed in X-ray wavelengths with ROSAT. In thethree cases where the galaxies are detected strongly, the nuclei of thegalaxies have X-ray extensions in the direction of the adjacent quasars.In all cases the active galaxies and bright quasars are located at theorigin of apparent lines or pairs of X-ray sources, some involvingfilamentary X-ray connections to fainter quasars or candidate bluestellar objects. A number of X-ray sources in these fields are found tobe in excess of average background values. The filaments and connectionshave measured fluxes of 0.1<~F_X_<~2x10^-13^erg/cm^2^/s and theytend to radiate more strongly in the harder end of the 0.1-2.4keV energyband. Tables of positions and properties of the detected X-ray sourcesin each field are given and candidates for optical identifications aredescribed.
