High-velocity OH megamasers in IRAS 20100−4156: evidence for a supermassive black hole

Abstract:

We report the discovery of new, high-velocity narrow-line components of the OH megamaser in IRAS 20100−4156. Results from the Australian Square Kilometre Array Pathfinder (ASKAP)'s Boolardy Engineering Test Array (BETA) and the Australia Telescope Compact Array (ATCA) provide two independent measurements of the OH megamaser spectrum. We found evidence for OH megamaser clumps at −409 and −562 km s−1 (blue-shifted) from the systemic velocity of the galaxy, in addition to the lines previously kn...
