VHE gamma-ray intranight variability from BL Lacertae during the extreme flaring state of 2022

K. Abe, S. Abe, A. Abhishek +297

BL Lacertae (BL Lac), the archetypal blazar of its subclass and one of the most studied blazars in the last decades, has undergone a series of major multi-wavelength outbursts sinc…

NOCTURNE. III. Unidentified variable emission in the nuclear regions of PKS 2153-69

Miguel Coloma Puga, Marco Berton, Pierpaolo Condò +4

Historically, the study of the central regions of Type 1 AGN has been limited by the combination of the host galaxy spectrum with strong emission from the accretion disk and NLR/BL…

NOCTURNE. I. The radio spectrum of narrow-line Seyfert 1 galaxies

M. Berton, E. Järvelä, S. Chen +8

The origin of the radio emission in active galactic nuclei (AGN) is still debated. Multiple physical mechanisms can contribute to the spectrum at these frequencies, including relat…

A long-term multiwavelength study of the flat spectrum radio quasar OP 313

Chiara Bartolini, Elina Lindfors, Andrea Tramacere +25

The Flat Spectrum Radio Quasar OP 313 is a high-redshift (z = 0.997) blazar that entered an intense gamma-ray active phase from November 2023 to March 2024, as observed by the Larg…

IXPE Observations of the Blazar Mrk 501 in 2022: A Multiwavelength View

L. Lisalda, E. Gau, H. Krawczynski +157

The blazar Markarian 501 (Mrk 501) was observed on three occasions over a 4-month period between 2022 March and 2022 July with the Imaging X-ray Polarimetry Explorer (IXPE). In thi…

The polarisation behaviour of OJ 287 viewed through radio, millimetre and optical observations between 2015 and 2017

J. Jormanainen, T. Hovatta, E. Lindfors +13

OJ 287 is a bright blazar with century-long observations, and one of the strongest candidates to host a supermassive black hole binary. Its polarisation behaviour between 2015 and…
