Fermi-LAT Observation of PSR B1259-63 during Its 2021 Periastron Passage

open access: yesUniverse, 2021
PSR B1259-63 is a γ-ray binary system, where the compact object is a pulsar. The system has an orbital period of 1236.7 days and shows peculiar γ-ray flares (in 100 MeV–300 GeV) after its periastron time.

Phase transitions and geothermodynamics of black holes in dRGT massive gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In this paper, we study the thermodynamics and geothermodynamics of spherical black hole solutions in dRGT massive gravity in a new extended phase space. Inspire by the work of Kastor et al.

Viscous attenuation of gravitational waves propagating through an inhomogeneous background

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We consider the propagation of gravitational waves in the late-time Universe in the presence of matter distribution inhomogeneities, and we also consider the cosmic fluid to be viscous.

Supergalactic Structure of Multiplets with the Telescope Array Surface Detector [PDF]

open access: yesEPJ Web of Conferences, 2019
Evidence of supergalactic structure of multiplets has been found for ultra-high energy cosmic rays (UHECR) with energies above 1019 eV using 7 years of data from the Telescope Array (TA) surface detector.

Mechanical Structure Design and Experimental Study of Gamma-ray Monitor for Small Satellite Payload

open access: yesApplied Sciences, 2022
In this paper, a novel mechanical structure for a gamma-ray monitor (GRM) is designed for a small satellite payload. Its structural stiffness, strength and dynamic response are directly related to the performance of the novel GRM, which must meet the ...

EXTRAGALACTIC HIGH-ENERGY TRANSIENTS: EVENT RATE DENSITIES AND LUMINOSITY FUNCTIONS [PDF]

open access: yes, 2015
Several types of extragalactic high-energy transients have been discovered, which include high-luminosity and low-luminosity long-duration gamma-ray bursts (GRBs), short-duration GRBs, supernova shock breakouts (SBOs), and tidal disruption events (TDEs ...

Action principle of Galilean relativistic Proca theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this paper, we discuss Galilean relativistic Proca theory in detail. We first provide a set of mapping relations, derived systematically, that connect the covariant and contravariant vectors in the Lorentz relativistic and Galilean relativistic ...
