Letter to the Editor Pairs of X-ray sources across Seyferts: the NGC4235 field

چکیده

Two strong X-ray sources are paired about equally distant across the Seyfert galaxyNGC4235. It is shown here that they are a BL Lac object and a quasar. Comparison with other associations of X-ray AGN’s with Seyferts reveals systematic alignments within about 20 degrees of the minor axis of the active galaxy. Fainter BSO candidates measured here suggest secondary associations of quasars with individual pair members and at closer distances to active galaxies.

Identification of X-ray sources< 1◦ from Seyfert galaxies

Excess numbers of X-ray sources around bright Seyfert galaxies have been demonstrated with significances of association up to 7.4 sigma (Radecke, preceding paper). The optical identification of these sources is shown here to be predominantly blue stellar objects (BSO’s) of which some are already catalogued as quasars. Excluding the two brightest Seyferts, a subset of 24 with apparent magnitudes...

X-ray sources< 1 degree from Seyfert galaxies

Archived PSPC observations of 26 Seyfert galaxies have been analyzed for brightX-ray sources out to the full extent of the field (< about 50′). Of all Seyferts known this represents a sample 88% complete to BT = 10 mag, 74% complete to 11 mag and 50% complete to 12 mag. Using the same reduction algorithm, 14 fields centered on stars at high galactic latitudes have been used as control fields. E...
