Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017

F. D'Ammando, C. M. Raiteri, M. Villata +94

We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…

Blazar spectral variability as explained by a twisting inhomogeneous jet

C. M. Raiteri, M. Villata

Blazar emission is dominated by non-thermal radiation from a relativistic jet pointing toward us, therefore undergoing Doppler beaming. This is responsible for flux enhancement and…

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…

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…

The WEBT campaign on the BL Lac object PG 1553+113 in 2013. An analysis of the enigmatic synchrotron emission

C. M. Raiteri, A. Stamerra, M. Villata +2

A multifrequency campaign on the BL Lac object PG 1553+113 was organized by the Whole Earth Blazar Telescope (WEBT) in 2013 April-August, involving 19 optical, two near-IR, and thr…

Discovery of a Highly Polarized Optical Microflare in the Blazar S5 0716+714 During 2014 WEBT Campaign

Gopal Bhatta, Arti Goyal, Michal Ostrowski +42

The occurrence of low-amplitude flux variations in blazars on hourly timescales, commonly known as microvariability, is still a widely debated subject in high-energy astrophysics.…
