NRAO Colloquium

Date: Fri. 10 Mar, 2017 11:00 am - 12:00 pm
Duration: 1 Hour
Location: NRAO

Dr. Yancy Shirley of the University of Arizona will present the NRAO-Socorro colloquium. His talk is titled "The Physical Properties of Massive Dense Clumps in Different Evolutionary Stages in the Milky Way." Followup molecular line observations of several thousand clumps in lines of NH3 and HCO+ with the GBT and SMT determine the thermal and turbulent state of the clumps. Clumps have been sorted into evolutionary categories by comparing the 1.1mm continuum with near/mid/far-infrared surveys, masers surveys, and radio continuum (VLA) surveys. Initial analysis of the ALMA observations probe fragmentation down to the core scales and are consistent with thermal Jean fragmentation in these massive clumps. 11 a.m. in the auditorium of the Domenici Science Operations Center (NRAO).
