Phase transitions and geothermodynamics of black holes in dRGT massive gravity
European 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.

High energy neutrino astrophysics [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 Astroparticle physics is a field rich of perspectives in investigating the ultra-high energy region which will never be accessible to man made machines. Many efforts are underway in order to detect the first cosmic neutrinos, messengers of the unobserved universe.

Soft scattering evaporation of dark matter subhalos by inner galactic gases
European Physical Journal C: Particles and Fields, 2023 The large gap between a galactic dark matter subhalo’s velocity and its own gravitational binding velocity creates the situation that small subhalos can be evaporated before dark matter thermalize with baryons due to the low binding velocity.

The Phenomena of High Energy Astrophysics [PDF]
, 2003 A brief summary of some highlights in the study of high energy astrophysical sources over the past decade is presented. It is argued that the great progress that has been made derives largely from the application of new technology to observation ...

Timescale Spectra in High Energy Astrophysics [PDF]
, 2002 A technique of timescale analysis performed directly in the time domain has been developed recently. We have applied the technique to studying rapid variabilities of hard X-rays from neutron star and black hole binaries, gamma-ray bursts and terrestrial ...

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

Viscous attenuation of gravitational waves propagating through an inhomogeneous background
European 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]
EPJ 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.
