Gamma-ray emission from particle illumination and shock-cloud interaction in the W51 Complex
Alan Sunny, Martina Cardillo
In the current era of very-high-energy (VHE) and ultra-high-energy (UHE) -ray astronomy, understanding Galactic PeVatrons and their acceleration mechanisms remains a primary ob…
Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes
K. Abe, S. Abe, J. Abhir +439
We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…
The Origin of Multi-TeV Gamma-rays in LHAASO J0341+5258 via Cosmic Ray Illumination of Molecular Clouds
Abhijit Roy, Alan Sunny, Martina Cardillo +2
The paper investigates the ultra‑high‑energy gamma‑ray emission from LHAASO J0341+5258, modeling it as cosmic‑ray particles accelerated by a past supernova remnant that illuminate…
Extreme Blazars Observed with MAGIC: Second Catalog Release
K. Abe, S. Abe, J. Abhir +353
Extremely high-peaked BL Lac objects - also named extreme blazars - are among the most energetic and persistent extragalactic accelerators in the Universe, defined by a synchrotron…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
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…
