Detection of the distant quasar OP 313 with the first Large-Sized Telescope of CTAO

K. Abe, S. Abe, J. Abhir +412

In December 2023, the Large-Sized Telescope prototype (LST-1) detected for the first time VHE -ray emission from the FSRQ OP~313 becoming the furthest blazar ever observed at V…

The January 2010 flare of Mrk421: Insights from a stochastic acceleration model

MAGIC collaboration, K. Abe, S. Abe +191

Mrk421 displayed its highest flux state ever observed in February of 2010 with very high TeV fluxes and interesting cross-band correlations and a spectral energy distribution (SED)…

A TeV-based Determination of the Local Extragalactic Background Light and its Consistency with Galaxy Counts and Direct Measurements

J. Baxter, A. Dominguez, J. D. Finke +5

The extragalactic background light (EBL), the cumulative radiation from all extragalactic sources, traces galaxy formation and cosmic evolution. High-energy rays attenuated vi…

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…

MAGIC observations of NGC 4278. The first low-luminosity radio galaxy with compact jets detected at TeV energies

S. Abe, J. Abhir, V. A. Acciari +189

The Large High Altitude Air Shower Observatory (LHAASO) Collaboration has recently reported the first detection at TeV energies of a low-luminosity radio galaxy, NGC 4278. The aim…

First detection of VHE gamma-ray signal from the FSRQ TON 0599

MAGIC Collaboration, K. Abe, S. Abe +245

TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…
