Lost in the curve: Investigating the disappearing knots in the blazar 3C 454.3

Efthalia Traianou, Thomas P. Krichbaum, José L. Gómez +21

One of the most well-known extragalactic sources in the sky, quasar 3C 454.3, shows a curved parsec-scale jet that has been exhaustively monitored with very-long-baseline interfero…

The Repeating Flaring Activity of Blazar AO 0235+164

Juan Escudero Pedrosa, Iván Agudo, Andrea Tramacere +27

Context. Blazar AO 0235+164, located at redshift z = 0.94, has undergone several sharp multi-spectral-range flaring episodes during the last decades. In particular, the episodes pe…

A Near Magnetic-to-kinetic Energy Equipartition Flare from the Relativistic Jet in AO 0235+164 during 2013-2019

Whee Yeon Cheong, Sang-Sung Lee, Sang-Hyun Kim +17

We present the multiwavelength flaring activity of the blazar AO 0235+164 during its recent active period from 2013 to 2019. From a discrete correlation function (DCF) analysis, we…

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…

IXPE and multi-wavelength observations of blazar PG 1553+113 reveal an orphan optical polarization swing

Riccardo Middei, Matteo Perri, Simonetta Puccetti +119

The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consen…

The RoboPol sample of optical polarimetric standards

D. Blinov, S. Maharana, F. Bouzelou +34

Optical polarimeters are typically calibrated using measurements of stars with known and stable polarization parameters. However, there is a lack of such stars available across the…
