X-ray observations of blazars with ASCA
Preliminary abstract:
We have analyzed 15 blazars observed with ASCA since the launch in 1993. A half of the observations were conducted in the multiwavelength campaigns. GeV gamma-ray emission has been detected from 9 of them. The synchrotron process by the relativistic electrons and the Comptonization of the synchrotron photons are thought to be the important radiation processes from blazars. The X-ray band is the "bridge" between the synchrotron and Compton spectrum. Therefore X-ray observation is crucial to study the mechanism of emission extending up to GeV or TeV gamma-rays. In this paper we present the observed properties of blazars in keV regime and its relation to other wavelength.
