High-energy multimessenger emission from galaxy clusters in the local universe
S. Hussain, Gabrijela Zaharijas, Klaus Dolag
Izvirni znanstveni članek
Oznake: high energy astrophysics;neutrino astronomy;gamma-ray astronomy;galaxy clusters;coma cluster;perseus cluster;
The origin of diffuse neutrinos and γ rays is unknown, and galaxy clusters hosting active galactic nuclei and starburst galaxies are the most probable sources of these cosmic messengers. In this work, we investigate the diffuse γ-ray and neutrino emission from the Virgo, Perseus, and Coma clusters u ...

High-energy neutrino and gamma ray emission from clusters-like Perseus
S. Hussain, Gabrijela Zaharijas, Klaus Dolag
Objavljeni znanstveni prispevek na konferenci
Oznake: galaxy clusters;AGN;cosmic-rays;neutrinos;gamma-rays;
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 emission from the central source, such as NGC1275, from the diffuse emission originating in the outskirts of the Perseu ...

Environmental dependence of AGN activity and star formation in galaxy clusters from Magneticum simulations
Gregor Rihtaršič, Veronica Biffi, Dunja Fabjan, Klaus Dolag
Izvirni znanstveni članek
Oznake: active galaxies;star formation;active galactic nuclei;
Context. The environment inside and on the outskirts of galaxy clusters has a profound impact on the star formation rate and active galactic nucleus (AGN) activity in cluster galaxies. While the overall star formation and AGN suppression in the inner cluster regions has been thoroughly studied in th ...

Properties of the diffuse gas component in filaments detected in the Dianoga cosmological simulations
Samo Ilc, Dunja Fabjan, Elena Rasia, Stefano Borgani, Klaus Dolag
Izvirni znanstveni članek
Oznake: galaxies clusters;intergalactic medium;large-scale structure;
Context. Cosmic filaments are observationally hard to detect. However, hydrodynamical cosmological simulations are ideal laboratories where the evolution of the cosmic web can be studied, and they allow for easier insight into the nature of the filaments. Aims. We investigate how the intrinsic prope ...
