[165.02] The Arecibo Methanol Maser Galactic Plane Survey

The Arecibo Methanol Maser Galactic Plane Survey (AMGPS) is a blind survey for 6.7 GHz methanol masers in the Galactic plane. 6.7 GHz methanol masers are thought to trace the very early stages of high-mass star formation, and are excellent tools for probing Galactic structure and understanding the formation process of massive stars. Our survey targets the Galactic plane between Galactic longitudes 35 < l < 55 degrees, and latitudes \midb\mid < 0.4 degrees, and is the most sensitive methanol maser blind survey carried out to date. The 3\sigma sensitivity of the survey is ~ 0.25 Jy, although fainter sources have been detected using 3D matched filtering techniques. The entire survey is expected to be completed by the end of December 2005. As of October 2005, a 7.7 square degree region has been surveyed, out of which we have detections of 47 methanol masers, 29 of which are new sources. I will present results from the survey, including the distribution of masers in the Galaxy, their counterparts at other wavelengths, and statistics on line-widths of individual maser features.
