Testing particle acceleration in blazar jets with continuous high-cadence optical polarization observations

Ioannis Liodakis, Sebastian Kiehlmann, Alan P. Marscher +44

Variability can be the pathway to understanding the physical processes in astrophysical jets, however, the high-cadence observations required to test particle acceleration models a…

The variability patterns of the TeV blazar PG 1553+113 from a decade of MAGIC and multi-band observations

MAGIC Collaboration, H. Abe, S. Abe +264

PG 1553+113 is one of the few blazars with a convincing quasi-periodic emission in the gamma-ray band. The source is also a very high-energy (VHE; >100 GeV) gamma-ray emitter. To b…

Observations of Low and Intermediate Spectral Peak Blazars with the Imaging X-ray Polarimetry Explorer

Herman L. Marshall, Ioannis Liodakis, Alan P. Marscher +145

We present X-ray polarimetry observations from the Imaging X-ray Polarimetry Explorer (IXPE) of three low spectral peak and one intermediate spectral peak blazars, namely 3C 273, 3…

Discovery of X-ray polarization angle rotation in active galaxy Mrk 421

Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert +140

The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can trac…

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…

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…
