ǂThe ǂdiffuse gamma-ray flux from clusters of galaxies
S. Hussain, Rafael Alves Batista, Elisabete M. De Gouveia Dal Pino, Klaus Dolag
Izvirni znanstveni članek
Oznake: galaxy clusters;gamma-rays;neutrinos;
The origin of the diffuse gamma-ray background (DGRB), the one that remains after subtracting all individual sources from observed gamma-ray sky, is unknown. The DGRB possibly encompasses contributions from different source populations such as star-forming galaxies, starburst galaxies, active galact ...

High-energy neutrino production in clusters of galaxies
S. Hussain, Rafael Alves Batista, Elisabete M. De Gouveia Dal Pino, Klaus Dolag
Izvirni znanstveni članek
Oznake: clusters of galaxies;AGN;neutrinos;gamma rays;cosmic rays;magnetic field;
Clusters of galaxies can potentially produce cosmic rays (CRs) up to very high energies via large-scale shocks and turbulent acceleration. Due to their unique magnetic-field configuration, CRs with energy ≤1017 eV can be trapped within these structures over cosmological time-scales, and generate sec ...

High-energy neutrino production in clusters of galaxies
S. Hussain, Rafael Alves Batista, Elisabete M. De Gouveia Dal Pino, Klaus Dolag

Oznake: astroparticle physics;galaxy clusters;gamma rays;neutrinos;cosmic rays;
In this work, we compute the contribution from clusters of galaxies to the diffuse neutrino background. Clusters of galaxies can potentially produce cosmic rays (CRs) up to very-high energies via large-scale shocks and turbulent acceleration. Due to their unique magnetic-field configuration, CRs wit ...

Propagation of cosmic rays and their secondaries in the intracluster medium
S. Hussain, Rafael Alves Batista, Elisabete M. De Gouveia Dal Pino, Klaus Dolag
Objavljeni znanstveni prispevek na konferenci
Oznake: cosmic rays;ICM;IGM;gamma rays;neutrinos;
We present results of the propagation of high-energy cosmic rays (CRs) and their secondaries in the intracluster medium (ICM). To this end, we employ three-dimensional cosmological magnetohydrodynamical simulations of the turbulent intergalactic medium to explore the propagation of CRs with energies ...

Oznake: High Energy Astrophysical Phenomena;cosmic rays;supernova remnants;Cherenkov Telescope Array Observatory;
This white paper briefly summarizes the importance of the study of relativistic cosmic rays, both as a constituent of our Universe, and through their impact on stellar and galactic evolution. The focus is on what can be learned over the coming decade through ground-based gamma-ray observations over ...

Oznake: ultra-high-energy cosmic rays;UHE photons;UHE neutrinos;the Global Cosmic-ray Observatory project;
The Global Cosmic-ray Observatory (GCOS) is a proposed large-scale observatory for studying ultra-high-energy cosmic particles, including ultra-high-energy cosmic rays (UHECRs), photons, and neutrinos. Its primary goal is to characterise the properties of the highest-energy particles in Nature wi ...
