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…
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-ra…
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 light…
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…
Precise dynamical masses of new directly imaged companions from combining relative astrometry, radial velocities, and Hipparcos-Gaia eDR3 accelerations
E. L. Rickman, E. Matthews, W. Ceva +7
Aims. With an observing time span of more than 20 years, the CORALIE radial-velocity survey is able to detect long-term trends in data corresponding to companions with masses and s…
Neutrinos, Cosmic Rays and the MeV Band
R. Ojha, H. Zhang, M. Kadler +23
The possible association of the blazar TXS 0506+056 with a high-energy neutrino detected by IceCube holds the tantalizing potential to answer three astrophysical questions: 1. Wher…
Multi-Physics of AGN Jets in the Multi-Messenger Era
B. Rani, M. Petropoulou, H. Zhang +20
Active galactic nuclei (AGN) with relativistic jets, powered by gas accretion onto their central supermassive black hole (SMBH), are unique laboratories for studying the physics of…
X-Ray and Gamma-Ray Polarization in Leptonic and Hadronic Jet Models of Blazars
Haocheng Zhang, Markus Boettcher
We present a theoretical analysis of the expected X-ray and gamma-ray polarization signatures resulting from synchrotron self-Compton emission in leptonic models, compared to the p…
