Review Talk by Physics and Astronomy Graduate student Sung-ju Kang

This is first results of N49 from the Herchel infrared survey of the Galactic Plane. Ioninzed(HII) regions are known to trigger the formation of stars by means of various physical mechanisms. Several HII regions have been studied individually in the context of triggered star formation, focusing on the associated neutral material and the young stellar population. These studies have shown that the expansion of HII regions can trigger the formation of new stars of all masses. They use Herschel-PACS and -SPIRE images from the Herschel infrared survey of the Galactic plane, Hi-GAL, to perform this study.
