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

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 ...

CHAMP cosmic rays [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We study interactions of cosmological relics, $X$, of mass $m$ and electric charge $qe$ in the galaxy, including thermalization with the interstellar medium, diffusion through inhomogeneous magnetic fields and Fermi acceleration by supernova shock waves.

One century of cosmic rays – A particle physicist's view

EPJ Web of Conferences, 2015
Experiments on cosmic rays and the elementary particles share a common history that dates back to the 19th century. Following the discovery of radioactivity in the 1890s, the paths of the two fields intertwined, especially during the decades after the ...

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

Cosmic rays and molecular clouds

, 2012
This paper deals with the cosmic-ray penetration into molecular clouds and with the related gamma--ray emission. High energy cosmic rays interact with the dense gas and produce neutral pions which in turn decay into two gamma rays.

Cosmic ray driven Galactic winds [PDF]

, 2016
The escape of cosmic rays from the Galaxy leads to a gradient in the cosmic ray pressure that acts as a force on the background plasma, in the direction opposite to the gravitational pull.
