Characterization of Markarian 421 during its most violent year: Multiwavelength variability and correlations

K. Abe, S. Abe, J. Abhir +212

Mrk 421 was in its most active state around early 2010, which led to the highest TeV gamma-ray flux ever recorded from any active galactic nuclei. We aim to characterize the multiw…

A Comparative Study of TESS Light Curve Extraction Methods Applied to Blazars

Ethan Poore, Michael Carini, Ryne Dingler +2

Blazars are characterized by largely aperiodic variability on timescales ranging from minutes to decades across the electromagnetic spectrum. The TESS (Transiting Exoplanet Survey…

K2 Optical Emission from OJ 287 and Other Gamma-Ray Blazars on Hours-to-Weeks Timescales from 2014-2018

Ann E. Wehrle, Michael Carini, Paul J. Wiita +5

We present second observations by K2 of OJ~287 and 7 other -ray AGNs obtained in 2017-2018, second and third observations of the lobe-dominated, steep spectrum quasar 3C~207, an…

Multiwavelength behaviour of the blazar OJ 248 from radio to γ-rays

M. I. Carnerero, C. M. Raiteri, M. Villata +4

We present an analysis of the multiwavelength behaviour of the blazar OJ 248 at z = 0.939 in the period 2006-2013. We use low-energy data (optical, near-infrared, and radio) obtain…

Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010

The MAGIC Collaboration, J. Aleksić, S. Ansoldi +251

A flare from the TeV blazar Mrk 421, occurring in March 2010, was observed for 13 consecutive days from radio to very high energy (VHE, E > 100 GeV) gamma-rays with MAGIC, VERITAS,…

Unusual Flaring Activity in the Blazar PKS 1424-418 during 2008-2011

S. Buson, F. Longo, S. Larsson +24

Context. Blazars are a subset of active galactic nuclei (AGN) with jets that are oriented along our line of sight. Variability and spectral energy distribution (SED) studies are cr…
