NRAO Colloquium

Date: Fri. 6 Mar, 2015 11:00 am - 12:00 pm
Duration: 1 Hour
Location: NRAO

Dr. Matt Lister, professor of physics at Purdue University, is the guest speaker for the NRAO/NM Colloquium. He will present "Jet Evolution in Active Galactic Nuclei." At many wavebands, the sky away from the galactic plane is dominated by active galactic nuclei (AGN) containing powerful jets that are pointed nearly directly at us. The observed properties of these "blazars" are heavily influenced by special relativistic effects, and have been extensively studied with the Very Long Baseline Array and other instruments. MOJAVE is a VLBA key project that is studying the structure and evolution of these jets on parsec-scales. Lister and his colleagues are currently conducting large scale multi-configuration VLA and LOFAR surveys of AGN samples to look for kiloparsec-scale indicators of jet precession, and to explore the relation between overall jet power, speed, and gamma-ray emission. 11 a.m. in the auditorium of the Domenici Science Operation Center (NRAO).
