Abstract (from CDS):

PKS 0208-512 and GRO J0516-609 have recently been identified as the most prominent members of a possible sub-class of blazar-type AGNs that are exceptionally bright at MeV energies (``MeV-blazars''). We summarize here the findings for GRO J0516-609 and present updated analysis results for PKS 0208-512 based on simultaneous observations with EGRET and COMPTEL. Significant time variability is clearly seen in the PKS 0208-512 spectrum at high as well as medium γ-ray energies. We present spectra suggesting a distinct spectral upturn from the EGRET energy regime into the COMPTEL regime. The presence of a pronounced spectral component at about 1-10MeV appears now well established for these sources.
