Abstract
We present current results of an ongoing survey for OH megamasers in lumino us infrared galaxies at the Arecibo Observatory.(1) The survey is now two-t hirds complete, and has resulted in the discovery of 35 new OH megamasers a t z > 0.1, 24 of which are presented in this paper. We discuss the properti es of each source in detail, including an exhaustive survey of the literatu re. We also place upper limits on the OH emission from 107 nondetections an d list their IR, radio, and optical properties. The survey detection rate i s one OH megamaser for every six candidates overall, but is a strong functi on of the far-IR luminosity of candidates and may depend on merger stage or on the central engine responsible for the IR luminosity in the merging gal axy pair. We also report the detection of IRAS 12032+1707, a new OH gigamas er.
