Propagation of cosmic rays and their secondaries in the intracluster medium
S. Hussain, Elisabete M. De Gouveia Dal Pino
Objavljeni znanstveni prispevek na konferenci
Oznake: Monte Carlo simulations;cosmic rays;intragalactic medium;
We present results of the propagation of high-energy cosmic rays (CRs) 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 between 1e14 and 1e19 ...

Neutrinos and gamma rays from galaxy clusters constrained by the upper limits of IceCube
S. Hussain, Elisabete M. De Gouveia Dal Pino, Giulia Pagliaroli
Izvirni znanstveni članek
Oznake: galaxy cluster;cosmic rays;gamma rays;neutrinos;
Clusters of galaxies possess the capability to accelerate cosmic rays (CRs) to very high energy up to ∼1018 eV due to their large size and magnetic field strength, which favor CR confinement for cosmological times. During their confinement, they can produce neutrinos and γ-rays out of interactions w ...

High-energy neutrino and gamma ray production in clusters of galaxies
S. Hussain, Giulia Pagliaroli, Elisabete M. De Gouveia Dal Pino
Objavljeni znanstveni prispevek na konferenci
Oznake: multimessenger astronomy;perseus cluster;gamma rays;neutrinos;cosmic rays;
We compute the contribution from clusters of galaxies to the diffuse neutrino and γ− ray background. Due to their unique magnetic-field configuration, cosmic rays (CRs) with energy ≤1e17 eV can be confined within these structures over cosmological time scales, and generate secondary particles, inc ...

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 ...
