High-energy observations of blazars: An update
High-energy X-ray emission from blazars probes the site(s) in the relativistic jet with the most energetic particles and fields. X-ray variability, and correlated X-ray and gamma-ray TeV variability, is an important tool to investigate the structure of the jet and to discriminate among models for the production of the emission at the highest energies. In this talk, I will review results from various multifrequency campaigns of blazars at X-rays from RXTE and SAX, and summarize recent observations with XMM-Newton which are shedding new light on our understanding of these sources. Support from an NSF CAREER grant is acknowledged.
