Synchrotron emission from the blazar PG 1553+113. An analysis of its flux and polarization variability
C. M. Raiteri, F. Nicastro, A. Stamerra +4
In 2015 July 29 - September 1 the satellite XMM-Newton pointed at the BL Lac object PG 1553+133 six times, collecting data for 218 hours. During one of these epochs, simultaneous o…
Multiband optical variability of the blazar OJ 287 during its outbursts in 2015 -- 2016
Alok C. Gupta, A. Agarwal, A. Mishra +31
We present recent optical photometric observations of the blazar OJ 287 taken during September 2015 -- May 2016. Our intense observations of the blazar started in November 2015 and…
The Extremes in Intra-Night Blazar Variability: The S4 0954+65 Case
Rumen Bachev, Anton Strigachev, Evgeni Semkov +4
We present results of optical observations of the extremely violently variable blazar S4 0954+65 on intra-night time scales. The object showed flux changes of up to 100% within a f…
Multifrequency Photo-polarimetric WEBT Observation Campaign on the Blazar S5 0716+714: Source Microvariability and Search for Characteristic Timescales
G. Bhatta, Ł. Stawarz, M. Ostrowski +43
Here we report on the results of the WEBT photo-polarimetric campaign targeting the blazar S5~0716+71, organized in March 2014 to monitor the source simultaneously in BVRI and near…
Exceptional outburst of the blazar CTA 102 in 2012: The GASP-WEBT campaign and its extension
V. M. Larionov, M. Villata, C. M. Raiteri +49
After several years of quiescence, the blazar CTA 102 underwent an exceptional outburst in 2012 September-October. The flare was tracked from gamma-ray to near-infrared frequencies…
A search for chaos in the blazar: W2R 1926+42 and its possible consequence
Banibrata Mukhopadhyay, Rumen Bachev, Anton Strigachev
We search for low-dimensional chaotic signatures in the optical lightcurve of the field blazar W2R 1926+42. The frequently used correlation integral method is employed in…
