Title of the communication: The broad-band spectra of blazars
Preliminary abstract (12 lines max.):
We have analysed ROSAT PSPC spectra of flat spectrum radio sources and collected multifrequency data for the available sample. We discuss the broad-band indices of sources detected with EGRET and compare them to those of sources not seen by EGRET. Additionally we try to derive constraints on the X-ray thru gamma-ray spectra of these objects (indicies and break energies) by extrapolating spectra from the ROSAT energy range with broken power laws and testing whether these spectra reproduce the Comptel and EGRET detections and spectral parameters.
