Dr. Betsy Mills of the NRAO is the guest speaker for the New Mexico NRAO/NM Colloquium. She will present "The Environment of an Unusual Starless Galactic Center Molecular Cloud." She is a post-doctoral researcher and a Jansky Fellow. Mills is studying the giant molecular cloud G0.253+0.016 or "The Brick" is a massive (M~10^5 solar masses) cloud. Its apparent lack of star formation given its large mass makes it unique in our Galaxy. Mills will present recent VLA observations of this cloud that provide new measurements of its temperature structure and kinematics. The results of these observations also include the detection of an unprecedented number of shock-excited methanol masers, and the first detection of weak, extended continuum emission, apparently due to the external ionization of the cloud. 11 a.m. in the auditorium at the Domenici Science Operations Center (NRAO).
