Variability and stability in optical blazar jets: the case of OJ287
C. Villforth, K. Nilsson, J. Heidt +1
OJ287 is a BL Lac object at redshift z=0.306 that has shown double-peaked bursts at regular intervals of ~12 yr during the last ~ 40 yr. Due to this behavior, it has been suggested…
A change in the optical polarization associated with a gamma-ray flare in the blazar 3C 279
LAT Collaboration, members of the 3C 279 multi-band campaign
It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet po…
Suzaku and Multi-wavelength Observations of OJ 287 during the Periodic Optical Outburst in 2007
Hiromi Seta, Naoki Isobe, Makoto S. Tashiro +10
Suzaku observations of the blazar OJ 287 were performed in 2007 April 10--13 and November 7--9. They correspond to a quiescent and a flaring state, respectively. The X-ray spectra…
Intranight polarization variability in radio-loud and radio-quiet AGN
C. Villforth, K. Nilsson, R. Ostensen +3
(Abriged) Intranight polarization variability in AGN has not been studied extensively so far. Studying the variability in polarization makes it possibly to distinguish between diff…
