APEX sub-mm monitoring of gamma-ray blazars
S. Larsson, L. Fuhrmann, A. Weiss +13
So far, no systematic long-term blazar monitoring programs and detailed variability studies exist at sub-mm wavelengths. Here, we present a new sub-mm blazar monitoring program usi…
Intra-day variability observations of S5 0716+714 over 4.5 years at 4.8 GHz
X. Liu, H. -G. Song, N. Marchili +5
We aim to search for evidence of annual modulation in the time scales of the BL Lac object S5 0716+714. The intra-day variability (IDV) observations were carried out monthly from 2…
Unification and physical interpretation of the radio spectra variability patterns in Fermi blazars and jet emission from NLSy1s
E. Angelakis, L. Fuhrmann, I. Nestoras +10
The F-GAMMA program is among the most comprehensive programs that aim at understanding the physics in active galactic nuclei through the multi-frequency monitoring of Fermi blazars…
VLBA monitoring of Mrk 421 at 15 and 24 GHz during 2011
R. Lico, M. Giroletti, M. Orienti +13
We present a preliminary analysis of new high resolution radio observations of the nearby TeV blazar Markarian 421 (z=0.031). This study is part of an ambitious multifrequency camp…
Radio-submm flares from blazars in a discontinuous jet model
Jörg P. Rachen, Max Häberlein, Felix Reimold +1
We present a model in which AGN jets are described by a dense series of plasma blobs, distributed in masses and velocities. The blobs expand and collide, and ultimately form a cont…
