Spectral properties of the Narrow-Line Seyfert 1 Quasar PG1211+143
Agnieszka Janiuk, Bozena Czerny, Grzegorz M. Madejski
We propose a theoretical model to explain the spectrum of the quasar PG1211+143 emitted in the Optical/X-ray bands. In particular, we suggest that the inner accretion disk may deve…

Ultraviolet Isotropic Emission from the Blazar 3C 279
E. Pian, A. Koratkar, L. Maraschi +7
Archival IUE SWP and HST FOS spectra show the presence of a relatively strong, broad Lyman alpha emission line superposed onto the UV spectral continuum of the blazar 3C 279. As op…

Gamma-ray flux variability in the sample of EGRET blazars
P. Magdziarz, R. Moderski, G. M. Madejski
We analyze average gamma-ray variability statistics for the sample of blazars detected by CGRO/EGRET. We re-reduce all the available EGRET observations and analyze light curves by…
