VLBI of the variable OH megmaser source IRAS02524+2046 |
|||||||||||||||||||
Abstract |
|||||||||||||||||||
We propose to map the 1667 and 1665 MHz OH emission in the OH megamaser galaxy IRAS 02524+2046. VLBI observations will test the interpretation of spectral line variability as interstellar scintillation (ISS) and provide a framework for studying the Galactic ionized ISM on sub-AU scales in subsequent single dish monitoring campaigns. The proposed reckoning between VLBI maps and ISS models will allow variability studies of more distant OH mega- masers to achieve super-VLBI resolution and greatly expand the sample of OH megamasers with spatial information. The structure of OH megamasers is intimately connected to the structure of massive starbursts and in some cases to massive black holes. We request 14 hours to observe IRAS 02524+2046. | |||||||||||||||||||
