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…
POLAMI Multi-Wavelength Polarization Study of AGN Jets: A Millimeter-Optical Comparison
C. Casadio, D. Blinov, I. Agudo +20
Millimeter-band polarimetry offers a powerful probe of AGN jets, accessing regions less affected by opacity and Faraday rotation than at longer radio wavelengths. As part of the PO…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
Investigating the mysterious nature of 1LHAASO J1740+0948u through deep XMM-Newton observations
G. Brunelli, G. Ponti, H. Zhang +4
1LHAASO J1740+0948u is a very-high-energy (VHE) source reported by LHAASO, with no counterpart at other wavelengths. It is located at 0.2° from PSR J1740+1000, a radio and gamma-r…
Search for Kink Events in Variable Fermi-LAT Blazars
P. Peñil, H. Zhang, J. Otero-Santos +10
This study explores the detection of Quasi-Periodic Oscillations (QPOs) in blazars as a method to identify kink events within their jets, utilizing both -ray and polarized ligh…
