DISCOVERY OF THE FIRST METHANOL (CH [subscript 3] OH) MASER IN THE ANDROMEDA GALAXY (M31)

We present the first detection of a 6.7 GHz Class II methanol (CH[subscript 3]OH) maser in the Andromeda galaxy (M31). The CH[subscript 3]OH maser was found in a VLA survey during the fall of 2009. We have confirmed the methanol maser with the new EVLA, in operation since 2010 March, but were unsucc...

description We present the first detection of a 6.7 GHz Class II methanol (CH[subscript 3]OH) maser in the Andromeda galaxy (M31). The CH[subscript 3]OH maser was found in a VLA survey during the fall of 2009. We have confirmed the methanol maser with the new EVLA, in operation since 2010 March, but were unsuccessful in detecting a water maser at this location. A direct application for this methanol maser is the determination of the proper motion of M31, such as was previously obtained with water masers in M33 and IC10. Unraveling the three-dimensional velocity of M31 would solve for the biggest unknown in the modeling of the dynamics and evolution of the Local Group of galaxies.
