1997AJ....114.2353C PROBES FOR NEARBY GALAXIES DAVID CRAMPTON AND G. GUSSIE Dominion Astrophysical Observatory. National Research Council of Canada.Victoria, B.C. V8X 4M6, Canada Electronic mail: crampton@dao.nrc.ca A. P. COWLEY AND P. C. SCHMIDTKE Department of Physics & Astronomy, Arizona State University, Tempe, Arizona 85287-1504 Electronic mail: surname@vela.la.asu.edu Received 1997 July 21; revised 1997 August 26; accepted 1997 August 26 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.
