Testing OH Megamaser Identification Methods in H i Surveys: Updated Source-flagging Algorithms and New Detections in ALFALFA

OH megamasers (OHMs) are extragalactic masers found primarily in gas-rich galaxy major mergers. To date, only ∼120 OHMs have been cataloged since their discovery in 1982, and efforts to identify distinct characteristics of OHM host galaxies have remained inconclusive. As radio astronomy advances wit...
