QSOs in the field of the Seyfert 1 galaxy NGC 5548.


Abstract (from CDS):

New spectrophotometric observations are presented for three blue stellar objects pinpointed as candidate optical identifications of ROSAT X-ray point sources in the field around the Seyfert 1 galaxy NGC 5548. They are shown to be medium-redshift QSOs. In combination with cataloged data on QSOs in several square degrees around NGC 5548, the areal density of QSOs immediately around the galaxy may exceed the average values determined from various surveys. This result, together with the configuration, suggests that these QSOs may be physically associated with NGC 5548.
