Peering into the Universe with Frequencies Below 1 GHz

Friday April 19, 2019
3:30 pm

 Presenter:  Dr. Tracy Clarke, Naval Research Lab (NRL)
 Series:  Physics and Astronomy Colloquium
 Abstract:  Low frequency interferometry is re-emerging as powerhouse for astrophysical studies. Hot-topic areas include the search for extrasolar planets, detecting fingerprints of the first stars, localizing and identifying the hosts of fast radio bursts (FRBs), and tracing shocks, turbulence and feedback in clusters of galaxies. In this talk I will discuss the revitalization of low frequency interferometry, including a discussion of current interferometers and capabilities. I will specifically highlight studies ongoing with the Long Wavelength array as well as a new commensal low frequency system we developed on the NRAO VLA that provides data 24/7 from this powerful interferometer.
 Host:  Gregory Taylor
 Location:  Room 125, Dane Smith Hall

Refreshments will be available before the colloquium, at 03:15 pm, in in the lobby of Dane Smith Hall.
