OH in Messier 82

Several new main line OH masers have been detected in the nearby starburst galaxy M82. Eight masers have been detected to 5 sigma, six of which are new detections. Observations covering both the 1665 and 1667 MHz lines with both the Very Large Array (VLA) and the Multi-Element Radio Linked Interferometer Network (MERLIN) have been used to accurately measure the positions and velocities of these features. Following analysis of the data, another six objects below 5 sigma, but with velocities consistent with the distribution inferred from the more certain detections, have been detected. These are classified as possible detections.
