Relativistic plasmas in low density environments

Lawrence Rudnick

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We have been developing techniques over the last several years to identify and study relativistic plasmas in low density environments. These relativistic plasmas may be the best or only available indicators of diffuse baryons in portions of the Warm-Hot Intergalactic Medium outside of rich galaxy clusters. Studying such faint radio synchrotron sources requires removal of confusion from both background radio galaxies and the foreground Milky Way. In these proceedings, we briefly summarize the techniques we are developing and some of our initial results. Our discoveries likely represent the "tip of the iceberg" to be exploited by the nascent generation of radio telescopes.
