RoboPol: The optical polarization of gamma-ray--loud and gamma-ray--quiet blazars
E. Angelakis, T. Hovatta, D. Blinov +25
We present average R-band optopolarimetric data, as well as variability parameters, from the first and second RoboPol observing season. We investigate whether gamma- ray--loud and…
The F-GAMMA program: Multi-frequency study of Active Galactic Nuclei in the Fermi era. Program description and the first 2.5 years of monitoring
L. Fuhrmann, E. Angelakis, J. A. Zensus +15
To fully exploit the scientific potential of the Fermi mission, we initiated the F-GAMMA program. Between 2007 and 2015 it was the prime provider of complementary multi-frequency m…
High-energy gamma-ray observations of the accreting black hole V404 Cygni during its June 2015 outburst
A. Loh, S. Corbel, G. Dubus +7
We report on Fermi/Large Area Telescope observations of the accreting black hole low-mass X-ray binary V404 Cygni during its outburst in June-July 2015. Detailed analyses reveal a…
Optical and Radio variability of the Northern VHE gamma-ray emitting BL Lac objects
E. J. Lindfors, T. Hovatta, K. Nilsson +9
We compare the variability properties of very high energy gamma-ray emitting BL Lac objects in the optical and radio bands. We use the variability information to distinguish multip…
Insights into the emission of the blazar 1ES 1011+496 through unprecedented broadband observations during 2011 and 2012
J. Aleksić, S. Ansoldi, L. A. Antonelli +161
1ES 1011+496 was discovered in very high energy (VHE, E >100 GeV) -rays with MAGIC in 2007. The absence of simultaneous data at lower energies led to a rather incomp…
