High-energy Neutrino and Gamma Ray Emission from Clusters-like Perseus
Saqib Hussain, Gabrijela Zaharijas, Klaus Dolag
We calculate the high-energy gamma-ray and neutrino emissions from galaxy clusters like Perseus that host active galactic nuclei (AGNs). Our primary objective is to distinguish the…
High-energy Multi-messenger Emission from Galaxy Clusters in the Local Universe
Saqib Hussain, Gabrijela Zaharijas, Klaus Dolag
The origin of diffuse neutrinos and -rays is unknown, and galaxy clusters hosting AGN and starburst galaxies are the most probable sources of these cosmic messengers. In this wo…
Chasing Gravitational Waves with the Cherenkov Telescope Array
Jarred Gershon Green, Alessandro Carosi, Lara Nava +563
The detection of gravitational waves from a binary neutron star merger by Advanced LIGO and Advanced Virgo (GW170817), along with the discovery of the electromagnetic counterparts…
Variability studies of active galactic nuclei from the long-term monitoring program with the Cherenkov Telescope Array
Guillaume Grolleron, Josefa Becerra González, Jonathan Biteau +13
Blazars are active galactic nuclei (AGN) with a relativistic jet oriented toward the observer. This jet is composed of accelerated particles which can display emission over the ent…
Dark matter searches in dwarf spheroidal galaxies with the Cherenkov Telescope Array
Francesco Gabriele Saturni, Michele Doro, Aldo Morselli +1
Dark matter (DM) is one of the major components in the Universe. However, at present its existence is still only inferred through indirect astronomical observations. DM particles c…
Neutrinos and gamma-rays from Galaxy Clusters constrained by the upper limits of IceCube
Saqib Hussain, Elisabete M. de Gouveia Dal Pino, Giulia Pagliaroli
Clusters of galaxies possess the capability to accelerate cosmic rays (CRs) to very high energy up to ~eV due to their large size and magnetic field strength which fav…
High-Energy Neutrino and Gamma Ray Production in Clusters of Galaxies
Saqib Hussain, Giulia Pagliaroli, Elisabete M. de Gouveia Dal Pino
We compute the contribution from clusters of galaxies to the diffuse neutrino and ray background. Due to their unique magnetic-field configuration, cosmic rays (CRs) with energ…
The Diffuse Gamma-Ray Flux from Clusters of Galaxies
Saqib Hussain, Rafael Alves Batista, Elisabete M. de Gouveia Dal Pino +1
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 enco…
High-Energy Neutrino Production in Clusters of Galaxies
Saqib Hussain, Rafael Alves Batista, Elisabete de Gouveia Dal Pino +1
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-hi…
High-Energy Neutrino Production in Clusters of Galaxies
Saqib Hussain, Rafael Alves Batista, Elisabete M. de Gouveia Dal Pino +1
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 config…
Cosmic-ray propagation in the turbulent intergalactic medium
R. Alves Batista, E. M. de Gouveia Dal Pino, K. Dolag +1
Cosmic rays (CRs) may be used to infer properties of intervening cosmic magnetic fields. Conversely, understanding the effects of magnetic fields on the propagation of high-energy…
