2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/15468We 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).4 pages, 1 figure, LaTex, uses newpasp.sty.
