F-GAMMA: Variability Doppler factors of blazars from multiwavelength monitoring
I. Liodakis, N. Marchili, E. Angelakis +8
Recent population studies have shown that the variability Doppler factors can adequately describe blazars as a population. We use the flux density variations found within the exten…
The IDV source J1128+5925, a new candidate for annual modulation?
K. E. Gabanyi, N. Marchili, T. P. Krichbaum +9
Short time-scale radio variations of compact extragalactic radio sources, known as IntraDay Variability, can be explained in at least some sources by a source-extrinsic effect, in…
Investigation of the correlation patterns and the Compton dominance variability of Mrk 421 in 2017
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +284
We present a detailed characterisation and theoretical interpretation of the broadband emission of the paradigmatic TeV blazar Mrk 421, with special focus on the multi-band flux co…
Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
LAT Collaboration, E. Angelakis, C. Bailyn +39
Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…
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…
A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
C. M. Raiteri, M. Villata, M. I. Carnerero +96
Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…
