Multiwavelength behaviour of the blazar 3C279: decade-long study from -ray to radio

V. M. Larionov, S. G. Jorstad, A. P. Marscher +84

We report the results of decade-long (2008-2018) -ray to 1 GHz radio monitoring of the blazar 3C 279, including GASP/WEBT, and data, as well as polarim…

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…

High accuracy measurement of gravitational wave back-reaction in the OJ287 black hole binary

Mauri J. Valtonen, L. Dey, R. Hudec +16

Blazar OJ287 exhibits large thermal flares at least twice every 12 years. The times of these flares have been predicted successfully using the model of a quasi-Keplerian eccentric…

Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters

Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5

Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…

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…

Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours

A. Goyal, L. Stawarz, S. Zola +109

We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-rays…
