Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 via Profile Likelihood with Gaussian Copula Correlation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
We present a joint multi-period analysis of axion-like particles (ALPs) using five sets of simultaneous Fermi-LAT and LHAASO observations of the TeV blazar Mrk~421. Photon-ALP osci…
Fermi-LAT View on Three Ultra-high-energy 1LHAASO Sources in the Region
Linjie Liu, Xian Hou, Pierrick Martin +1
Using more than 17 yr of Fermi-LAT data, we performed a detailed investigation of the complex region, which encompasses the three ultra-high-energy source…
Revisiting Very High Energy Gamma-Ray Absorption in Cosmic Propagation under the Combined Effects of Axion-Like Particles and Lorentz Invariance Violation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
Very-high-energy (VHE; GeV) gamma rays are expected to experience strong attenuation during cosmological propagation due to electron-positron pair production on the…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
Constraints on Extragalactic Background Light using TeV Observations of BL Lacertae objects
Longhua Qin, Jiancheng Wang, Quangui Gao +5
The extragalactic background light (EBL) in the IR to UV bands partly absorbs very high energy (VHE, 100GeV) ray photons travelling over cosmological distances via pai…
New simulations of the X-ray spectra and polarizations of accretion-disc corona systems with various geometrical configurations I. Model Description
Xiao-lin Yang, Jian-cheng Wang, Chu-yuan Yang
Energetic X-ray radiations emitted from various accretion systems are widely considered to be produced by Comptonization in the hot corona. The corona and its interaction with the…
