Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
Physical Conditions and Variability Processes in AGN Jets through Multi-Frequency Linear and Circular Radio Polarization Monitoring
Ioannis Myserlis, Emmanouil Angelakis, Alex Kraus +3
Radio polarimetry is an invaluable tool to investigate the physical conditions and variability processes in active galactic nuclei (AGN) jets. However, detecting their linear and c…
Robopol: Optical polarisation monitoring of blazars
Emmanouil Angelakis, Dmitry Blinov, Markus Böttcher +5
The RoboPol program has been monitoring the -band linear polarisation parameters of an unbiased sample of 60 gamma-ray-loud blazars and a "control" sample of 15 gamma-ray-quite…
Detecting the Elusive Blazar Counter-Jets
I. Liodakis, V. Pavlidou, E. Angelakis
Detection of blazar pc scale counter-jets is difficult, but it can provide invaluable insight into the relativistic effects, radiative processes and the complex mechanisms of jet p…
Optical polarization of high-energy BL Lac objects
T. Hovatta, E. Lindfors, D. Blinov +9
We investigate the optical polarization properties of high-energy BL Lac objects using data from the RoboPol blazar monitoring program and the Nordic Optical Telescope. We wish to…
Inner jet kinematics and the viewing angle towards the γ-ray narrow-line Seyfert 1 galaxy 1H 0323+342
L. Fuhrmann, V. Karamanavis, S. Komossa +9
Near-Eddington accretion rates onto low-mass black holes are thought to be a prime driver of the multi-wavelength properties of the narrow-line Seyfert 1 (NLS1) population of activ…
