NRAO Special Colloquium

Date: Thu. 15 Dec, 2016 10:00 am - 11:00 am
Duration: 1 Hour
Location: NRAO

Rachel Friesen of the Dunlap Institute for Astronomy and Astrophysics is the guest speaker for a NRAO-Socorro special colloquium. Her talk is titled "Mass Assembly in Star-forming Clouds from Filaments to Disks." Recent surveys of dust continuum emission within Galactic star-forming regions have revealed the ubiquity of filamentary structures in molecular clouds. The prevalence of filaments within star-forming regions raises the tantalizing possibility that the star formation efficiency in molecular clouds is strongly dependent on how these dense filaments form and evolve. Using a summary of recent GBT, VLA and ALMA results, Friesen will show how the combined analysis of gas dynamics and chemistry in star-forming regions is critical for testing models of filamentary formation and evolution. She also will present early science results from the Green Bank Ammonia Survey (GAS) that is mapping the dense molecular gas of all the major star-forming molecular clouds within 500 pc with the GBT. 10 a.m. in the auditorium of the Domenici Science Operations Center (NRAO).
