Search for AGN counterparts of unidentified Fermi-LAT sources with optical polarimetry: Demonstration of the technique
N. Mandarakas, D. Blinov, I. Liodakis +12
The third Fermi-LAT catalog (3FGL) presented the data of the first four years of observations from the Fermi Gamma-ray Space Telescope mission. There are 3034 sources, 1010 of whic…
High cadence, linear and circular polarization monitoring of OJ 287 - Helical magnetic field in a bent jet
I. Myserlis, S. Komossa, E. Angelakis +5
We present a multi-frequency, dense radio monitoring program of the blazar OJ287 using the 100m Effelsberg radio telescope. We analyze the evolution in total flux density, linear a…
Optical polarisation variability of narrow line Seyfert 1 galaxies
E. Angelakis, S. Kiehlmann, I. Myserlis +6
We have monitored the R-band optical linear polarisation of ten jetted NLSy1 galaxies with the aim to quantify their variability and search for candidate long rotation of the polar…
Optical polarisation variability of radio loud narrow line Seyfert 1 galaxies. Search for long rotations of the polarisation plane
E. Angelakis, S. Kiehlmann, I. Myserlis +5
Narrow line Seyfert 1 galaxies (NLSy1s) constitute the AGN subclass associated with systematically smaller black hole masses. A few radio loud ones have been detected in MeV -- GeV…
Multi-wavelength characterization of the blazar S5~0716+714 during an unprecedented outburst phase
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +187
The BL Lac object S5~0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC obs…
Effelsberg Monitoring of a Sample of RadioAstron Blazars: Analysis of Intra-Day Variability
Jun Liu, Hayley Bignall, Thomas P. Krichbaum +6
We present the first results of an ongoing intra-day variability (IDV) flux density monitoring program of 107 blazars, which were selected from a sample of RadioAstron space very l…
