High-Energy Multimessenger Transient Astrophysics [PDF]
The recent discoveries of high-energy cosmic neutrinos and gravitational waves from astrophysical objects have led to a new era of multimessenger astrophysics. In particular, electromagnetic follow-up observations triggered by these cosmic signals have proved to be highly successful and have brought about new opportunities in time-domain astronomy. We

High energy neutrino astrophysics [PDF]
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.

Timescale Spectra in High Energy Astrophysics [PDF]
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 ...

The Phenomena of High Energy Astrophysics [PDF]
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 ...

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

Updates on the Hotspot and the Perseus-Pisces supercluster Excess Observed by the Telescope Array Experiment [PDF]
The Telescope Array (TA) experiment, the largest observatory studying ultra-high energy cosmic rays in the northern hemisphere, has reported evidence for two medium-scale anisotropies.

Soft scattering evaporation of dark matter subhalos by inner galactic gases
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.

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

Similarity Properties and Scaling Laws of Radiation Hydrodynamic Flows in Laboratory Astrophysics [PDF]
The spectacular recent development of modern high-energy density laboratory facilities which concentrate more and more energy in millimetric volumes allows the astrophysical community to reproduce and to explore, in millimeter-scale targets and during ...

Viscous attenuation of gravitational waves propagating through an inhomogeneous background
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.
