Published in Jun 2013
Spitzer surveys of the inner Galactic Plane (GLIMPSE I & II) revealed a promising new diagnostic for identifying actively accreting (proto)stars: extended excess emission in the IRAC 4.5 micron band, believed to trace shocked molecular gas in active protostellar outflows. We will present initial results from our search for extended excess 4.5 micron sources in the outer Galaxy GLIMPSE360 survey, focusing on the area of the survey associated with the Perseus arm.
