We describe new implementations of leptonic and hadronic models for the broadband
emission from relativistic jets in active galactic nuclei in a temporary steady state. For the …

Blazars are the most violent steady/recurrent sources of high-energy gamma-ray emission in
the known Universe. They are prominent emitters of electromagnetic radiation throughout …

Blazars are a class of jet-dominated active galactic nuclei with a typical double-humped
spectral energy distribution. It is of common consensus that the synchrotron emission is …

We extend a method for modeling synchrotron and synchrotron self-Compton radiations in
blazar jets to include external Compton (EC) processes. The basic model assumption is that …

We present two-epoch, multifrequency complete modeling of Mrk 501 broad band emission
from the radio frequencies up to the very high gamma ray regime as observed during April …

We present a detailed parameter study of the time-dependent electron injection and
kinematics and the self-consistent radiation transport in jets of intermediate-and low …

Blazar subclasses ranging from flat-spectrum radio quasars (FSRQs) through low-frequency–
peaked BL Lac objects (LBLs) to high-frequency–peaked BL Lac objects (HBLs) exhibit a …

We present UBVRI light curves of BL Lacertae from May 2000 to January 2001, obtained by
24 telescopes in 11 countries. More than 15 000 observations were performed in that period …

In an effort to locate the sites of emission at different frequencies and physical processes
causing variability in blazar jets, we have obtained high time-resolution observations of BL …

Of the blazars detected by EGRET in GeV γ-rays, 3C 279 is not only the best observed by
EGRET but also one of the best monitored at lower frequencies. We have assembled 11 …
