Polarized Blazar X-rays imply particle acceleration in shocks
Ioannis Liodakis, Alan P. Marscher, Iván Agudo +125
Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $\sim 1…
Kinematics of Parsec-Scale Jets of Gamma-Ray Bright Blazars at 43 GHz during Ten Years of the VLBA-BU-BLAZAR Program
Zachary R. Weaver, Svetlana G. Jorstad, Alan P. Marscher +7
We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample of -ray bright blazars monitored roughly monthly with the Very Long Baseline Array at 43 G…
New jet feature in the parsec-scale jet of the blazar OJ287 connected to the 2017 teraelectronvolt flaring activity
R. Lico, C. Casadio, S. G. Jorstad +16
In February 2017 the blazar OJ287, one of the best super-massive binary-black-hole-system candidates, was detected for the first time at very high energies (VHEs; E>100GeV) with th…
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…
