NRAO Colloquium

Date: Fri. 27 Mar, 2015 11:00 am - 12:00 pm
Duration: 1 Hour
Location: NRAO

Dr. Ken Kellermann of the NRAO will deliver the weekly colloquium. He is a senior scientist at the NRAO and a research professor at the University of Virginia. His talk is "Radio Loud and Radio Quiet Quasars." He will discuss the bizarre circumstances surrounding the discovery of quasars through their strong radio emission, followed by the discovery of their more populous radio quiet counterpart. He will also describe the results of two VLA programs which suggest that the radio emission from radio quiet quasars is mostly due to star formation in the host galaxy. Finally, he will review what we have learned from VLBA observations of radio loud quasars as well as the challenges presented by the recent space VLBI observations of high brightness temperatures in some quasars. 11 a.m. in the auditorium of the Domenici Science Operations Center (NRAO).
