Title: The Youngest Massive Star Clusters: the Closeup Views from ALMA and TEXES
Abstract: The deeply embedded star clusters of starburst galaxies are the most extreme form of star formation in the local Universe. With sizes of only a few parsec, they can hold thousands of OB stars younger than 5 Myr and stellar masses of 106M⊙. These clusters have star formation efficiency at least 10 times greater than typical Galactic sources, and can be powerful sources of local cloud heating and metal enrichment. With new infrared, radio and sub-millimeter observatories it is now possible to measure ions, molecules and dust in these clusters with subarcsecond resolution and 3km s−1 velocity resolution. This talk will focus on ALMA , SMA , and TEXES observations of massive clusters in nearby dwarf galaxies and what they tell us about triggering, feedback, emergence and enrichment issues.
