Long-term optical monitoring of TeV emitting Blazars
K. Nilsson, E. Lindfors, L. O. Takalo +17
We present 10 years of R-band monitoring data of 31 northern blazars which were either detected at very high energy (VHE) gamma rays or listed as potential VHE gamma-ray emitters.…
Gamma-ray and Optical Oscillations of 0716+714, MRK 421, and BL Lac
A. Sandrinelli, S. Covino, A. Treves +12
We examine the 2008-2016 -ray and optical light curves of three bright BL Lac objects, 0716+714, MRK 421, BL Lac, which exhibit large structured variability. We searched for per…
The RINGO2 and DIPOL Optical Polarisation Catalogue of Blazars
H. Jermak, I. A. Steele, E. Lindfors +9
We present ~2000 polarimetric and ~3000 photometric observations of 15 gamma-ray bright blazars over a period of 936 days (11/10/2008 - 26/10/2012) using data from the Tuorla blaza…
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…
MAGIC detection of short-term variability of the high-peaked BL Lac object 1ES 0806+524
MAGIC Collaboration, J. Aleksić, S. Ansoldi +152
The high-frequency-peaked BL Lac (HBL) 1ES 0806+524 (z = 0.138) was discovered in VHE rays in 2008. Until now, the broad-band spectrum of 1ES 0806+524 has been only poorly char…
The 2009 multiwavelength campaign on Mrk 421: Variability and correlation studies
MAGIC Collaboration, J. Aleksić, S. Ansoldi +270
We performed a 4.5-month multi-instrument campaign (from radio to VHE gamma rays) on Mrk421 between January 2009 and June 2009, which included VLBA, F-GAMMA, GASP-WEBT, Swift, RXTE…
