Multi-year characterisation of the broad-band emission from the intermittent extreme BL Lac 1ES~2344+514

H. Abe, S. Abe, V. A. Acciari +232

The BL Lac 1ES 2344+514 is known for temporary extreme properties (e.g., a shift of the synchrotron SED peak energy above 1keV). While those extreme states were so fa…

X-ray Polarization Observations of BL Lacertae

Riccardo Middei, Ioannis Liodakis, Matteo Perri +143

Blazars are a class of jet-dominated active galactic nuclei with a typical double-humped spectral energy distribution. It is of common consensus the Synchrotron emission to be resp…

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…

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…

Investigation of the correlation patterns and the Compton dominance variability of Mrk 421 in 2017

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +284

We present a detailed characterisation and theoretical interpretation of the broadband emission of the paradigmatic TeV blazar Mrk 421, with special focus on the multi-band flux co…

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…
