Active Galactic Nuclei (AGNs) are some of the most distant objects known in the universe. Quasars, blazers, and Seyfert galaxies are all categorized as AGNs. One of the interesting characteristics of AGNs is that they vary in brightness over a variety of time scales including long term (years or decades), intraday (days or weeks), and very short periods (hours or minutes). Using the Morehead State University 21m Space Tracking Antenna we can measure short term variations (microvariability) of the radio frequency radiation of these distant objects. By monitoring the microvariability in the atomic hydrogen line at 1420 MHz we may be able to determine if the variability is due the internal processes of these objects or due to the intervening medium, and to provide insight into the nature and process of the AGN central engines. Initial observations of a set of target AGNs have been undertaken. These data sets will be correlated with simultaneous optical (Bell observatory) and gamma ray (GLAST) observations to produce broad band, multiwavelength observations of a target set of AGNs. This project is supported by the Kentucky Space Grants Consortium.
