Emission Line Variability during a Nonthermal Outburst in the Gamma-Ray Bright Quasar 1156+295

Melissa K. Hallum, Svetlana G. Jorstad, Valeri M. Larionov +18

We present multi-epoch optical spectra of the -ray bright blazar 1156+295 (4C +29.45, Ton 599) obtained with the 4.3~m Lowell Discovery Telescope. During a multi-wavelength outb…

Repeated pattern of gamma-ray flares in the lightcurve of the blazar 3C 279

D. Blinov, S. G. Jorstad, V. M. Larionov +10

The optical polarization plane of some blazars occasionally exhibits smooth hundred degree long rotations. Multiple theoretical models have been proposed to explain the nature of s…

The complex variability of blazars: Time-scales and periodicity analysis in S4 0954+65

C. M. Raiteri, M. Villata, V. M. Larionov +3

Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of the BL Lac object S4 0954+65 with data acquired in 2019-2020 by the Trans…

Parameters of the type-IIP supernova SN 2012aw

A. A. Nikiforova, P. V. Baklanov, S. I. Blinnikov +7

We present the results the photometric observations of the Type IIP supernova SN 2012aw obtained for the time interval from 7 till 371 days after the explosion. Using the previousl…

VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020

V. A. Acciari, S. Ansoldi, L. A. Antonelli +230

Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…

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…
