Detection of optical quasi-periodic oscillation in the blazar 3C 454.3

Karan Dogra, Alok C. Gupta, C. M. Raiteri +83

We analyzed 19 years of -band data of the blazar 3C 454.3 from the Whole Earth Blazar Telescope (WEBT) archive, along with new data from its members and from public archives suc…

Multiband Optical Variability of the Blazar 3C 454.3 on Diverse Timescales

Karan Dogra, Alok C. Gupta, C. M. Raiteri +79

Due to its peculiar and highly variable nature, the blazar 3C 454.3 has been extensively monitored by the WEBT team. Here, we present for the first time these long-term optical flu…

The dual nature of blazar fast variability. Space and ground observations of S5 0716+714

C. M. Raiteri, M. Villata, D. Carosati +39

Blazar S5 0716+714 is well-known for its short-term variability, down to intra-day time-scales. We here present the 2-min cadence optical light curve obtained by the TESS space tel…

Multi-Wavelength Variability of BL Lacertae Measured with High Time Resolution

Zachary R. Weaver, K. E. Williamson, S. G. Jorstad +54

In an effort to locate the sites of emission at different frequencies and physical processes causing variability in blazar jets, we have obtained high time-resolution observations…

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…
