1992AJ....103..728B HYDROXYL IN GALAXIES. I. SURVEYS WITH THE NRAO 300 ft TELESCOPE WILLEM A. BAAN Arecibo Observatory, P.O. Box 995, Arecibo, Puerto Rico 00613 AUBREY HASCHICK Haystack Observatory, Westford, Massachusetts 01886 CHRISTIAN HENKEL Max Planck Institut fur Radioastronomie, 69 Auf dem Hugel, D-5300 Bonn 1, Germany Received 26 June 1991; revised 29 October 1991 ABSTRACT Four sessions on the 300 ft telescope during 1984-1987 have been used to search for hydroxyl in galaxies. The surveys of a sample of 321 galaxies has produced a total of seven megamaser detections and four detections of absorption. Three detections of OH megamasers are reported in this paper: IR 15065 - 1107, IR 22025 + 4205, and IR 22491 - 1808; the other megamasers have been reported earlier. Detections are reported for three new OH absorption sources: IR 03134 - 0236, IR 14566 - 1629, and IR 16577 + 5900. The observing sample contains sources from a variety of catalogs and represents different selection criteria. The results for the whole sample confirm that FIR luminosity and color criteria used for present surveys are indeed optimized for finding megamasers. The results also confirm that detecting distant high luminosity OH megamasers is considerably more successful than finding nearby weak masers.
