J/AJ/114/2353       AGNs and QSOs behind nearby galaxies       (Crampton+, 1997)

Probes for nearby galaxies. Crampton D., Gussie G., Cowley A.P., Schmidtke P.C. <Astron. J. 114, 2353 (1997)> =1997AJ....114.2353C
ADC_Keywords: Active gal. nuclei ; QSOs ; Magnitudes ; Redshifts Abstract: Data are given for 16 extragalactic objects (predominantly AGN) behind the Magellanic Clouds and for 146 quasar candidates behind the nearby galaxies NGC 45, 185, 253, 2366, 2403 and 6822, IC 1613, M31, and M33. The Magellanic Cloud objects were identified by their X-ray emission, and precise optical and X-ray positions and optical photometry and spectra are presented for all of these. The quasar candidates surrounding the other nearby galaxies were identified through a CFHT slitless spectral survey. Although redshifts for only eight of these candidates have been obtained, previous observations indicate that the majority are likely to be quasars. A subsample of 49 of the brighter objects could confidently be used, in addition to the Magellanic Cloud sources, as probes of the gas in nearby galaxies for rotation curve studies, for studies of their halos, for comparison with higher redshift QSO absorption lines, or as references for proper motion studies.
