Blazars and INTEGRAL

Chinese Journal of Astronomy and Astrophysics, 2006
We refer to analysis of the ESA INTEGRAL satellite data for specific class of active galactic nuclei - blazars. These objects represent promising sources to be observed by INTEGRAL, especially during their active states. Suitable strategy for the future analysis is proposed and discussed.

Variability of Blazars

Journal of Astrophysics and Astronomy, 2011
Variability is one of the characteristics of blazars. The rapid variability is superposed on the long term variation. In this work, the variability on different time scales, such as intra-day (IDV), short-term (STV) and long-term (LTV) variations are presented for some sources.

Flares in Blazars

2009
Blazars are active galactic nuclei characterized by strong, nearly pure non-thermal radiations; these extend across the electromagnetic spectrum, from radio frequencies to the most energetics γ rays observed, in some cases up to TeV energies.
