Radiation Backgrounds at Cosmic Dawn: X-Rays from Compact Binaries [PDF]

, 2016
We compute the expected X-ray diffuse background and radiative feedback on the intergalactic medium (IGM) from X-ray binaries prior to and during the epoch of reionization. The cosmic evolution of compact binaries is followed using a population synthesis

Light Element Evolution and Cosmic Ray Energetics [PDF]

, 1999
Using cosmic-ray energetics as a discriminator, we investigate evolutionary models of LiBeB. We employ a Monte Carlo code which incorporates the delayed mixing into the ISM both of the synthesized Fe, due to its incorporation into high velocity dust ...

Messengers of the Universe-Cosmic Rays Exploring Supermassive Black Holes

Galaxies, 2020
Cosmic rays were discovered over one hundred years ago but there are still unsolved problems. One of the hot problems is the origin of cosmic rays of the highest energies.

The GRAND project and GRANDProto300 experiment [PDF]

EPJ Web of Conferences, 2019
The Giant Array for Neutrino Detection (GRAND) is a proposal for a giant observatory of ultra-high energy cosmic particles (neutrinos, cosmic rays and gamma rays). It will be composed of twenty subarrays of 10 000 antennas each, totaling a detection area

Slow Diffusion of Cosmic-Rays around a Supernova Remnant [PDF]

, 2010
We study the escape of cosmic-ray protons accelerated at a supernova remnant (SNR). We are interested in their propagation in interstellar medium (ISM) after they leave the shock neighborhood where they are accelerated, but when they are still near the ...

The origin of cosmic rays and TeV gamma-ray astronomy

EPJ Web of Conferences, 2013
Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...

Diffuse Emission of Galactic High-energy Neutrinos from a Global Fit of Cosmic Rays

The Astrophysical Journal, 2023
In the standard picture of Galactic cosmic rays, a diffuse flux of high-energy gamma rays and neutrinos is produced from inelastic collisions of cosmic-ray nuclei with the interstellar gas.

ON THE E/P-COSMIC RAYS AS MEDIATORS OF VISCOUS FORCES THAT CREATE SHOCK AND VORTEX STRUCTURES IN THE RADIO GALAXIES

Odessa Astronomical Publications, 2016
There are for the galaxies of FRII type (like Cygnus A) studied a number of hydrodynamic and kinetic processes to transport of magnetized plasma with cosmic rays, and a stratification process of RG-lobe because of e\p-cosmic rays.

Deciphering the Interplay Between Wetting and Chemo‐Mechanical Fracture in Lithium‐Ion Battery Cathode Materials

Advanced Functional Materials, EarlyView.
The fundamental intricate couplings between electrolyte wetting and fracture evolution are investigated in large single‐crystal V2O5 samples using both experimental techniques and simulations. Both approaches reveal consistent fracture patterns and lithium distribution concentration maps influenced by the wetting mechanism.

Role of line-of-sight cosmic ray interactions in forming the spectra of distant blazars in TeV gamma rays and high-energy neutrinos

, 2011
Active galactic nuclei (AGN) can produce both gamma rays and cosmic rays. The observed high-energy gamma-ray signals from distant blazars may be dominated by secondary gamma rays produced along the line of sight by the interactions of cosmic-ray protons ...
