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…

Multi-wavelength picture of the misaligned BL Lac object 3C 371

J. Otero-Santos, C. M. Raiteri, A. Tramacere +52

The BL Lac object 3C 371 is one of the targets that are regularly monitored by the Whole Earth Blazar Telescope (WEBT) Collaboration to study blazar variability on both short and l…

A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour

C. M. Raiteri, M. Villata, M. I. Carnerero +96

Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…

A Two-Week Monitoring Campaign on Mrk 421

W. Peter Maksym, Ioannis Liodakis, M. Lynne Saade +153

X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the firs…

The Method of Searching for Rotations of the Polarization Position Angle of Quasars

S. S. Savchenko, D. A. Morozova, S. G. Jorstad +11

Observations of quasars show that the polarization position angle of the emission coming from them varies greatly over time, including periods called rotations during which the ang…

X-ray and multiwavelength polarization of Mrk 501 from 2022 to 2023

Chien-Ting J. Chen, Ioannis Liodakis, Riccardo Middei +143

We present multiwavelength polarization measurements of the luminous blazar Mrk~501 over a 14-month period. The 2--8 keV X-ray polarization was measured with the Imaging X-ray Pola…

Optical variability of the blazar 3C 371: from minute to year timescales

J. Otero-Santos, C. M. Raiteri, J. A. Acosta-Pulido +41

The BL Lac object 3C 371 has been observed by the Transiting Exoplanet Survey Satellite (\textit{TESS}) for approximately a year, between July 2019 and July 2020, with an unmatched…
