Query: A Search for OH Megamasers at z > 0.1: Preliminary Results   We report the discovery of 11 OH megamasers and one OH absorber, along with
upper limits on the OH luminosity of 53 other luminous infrared galaxies at z >
0.1. The new megamasers show a wide range of spectral properties, but are
consistent with the extant set of 55 previously reported objects, 8 of which
have z > 0.1. The new OH detections are the preliminary results of a OH
megamaser survey in progress at the Arecibo Observatory, which is expected to
produce several dozen detections and calibrate the luminosity function of OH
megamasers to the low-redshift galaxy merger rate (0.1 < z < 0.2).
