Monitoring Radio Frequency Flux of Extragalactic Sources

Jeff Scargle visited the radio astronomy group at the California Institute of Technology headed by Prof. Anthony Readhead. This group has begun a large program of monitoring the radio frequency flux of about 1,000 extragalactic sources of variable luminosity (mostly active galactic nuclei), using the 40 meter dish of the Owens Valley Radio Observatory. The program is a collaboration with the Fermi Gamma Ray Space Telescope. Scargle will participate in the cross-analysis of the data from Fermi and the OVRO telescopes.
