Extragalactic water masers in bright IRAS sources

Abstract

We report the results of a search for 22 GHz water maser emission in IRAS-bright galaxies, using the 100-m Effelsberg telescope. In particular, we present the details of four new maser detections (IC342, NGC2146, NGC3556, and Arp299) and follow-up interferometric studies. A comparison between water maser detection rates derived in the present study and those in previous similar surveys is also presented.Comment: 4 pages, 2 figures, to appear in "The Neutral ISM in Starburst Galaxies", ASP Conference Series, Volume xxx, 2003, eds.
