In recent years, the outskirts of galaxy clusters have emerged as one new frontiers and unique laboratories for studying growth large scale structure in universe. Modern cosmological hydrodynamical simulations make firm testable predictions thermodynamic chemical evolution X-ray emitting intracluster medium. However, Sunyaev-Zeldovich effect observations revealed enigmatic disagreements with theoretical predictions, which motivated deeper investigations a plethora astrophysical processes...
Abstract Active galactic nuclei (AGNs) are widely believed to be one of the promising acceleration sites ultrahigh-energy cosmic rays (CRs). Essentially, AGNs powered by gravitational energy matter falling into supermassive black holes. However, conversion efficiency kinetic CRs in AGNs, which is defined as baryon loading factor η p , not well known yet. After being accelerated, high-energy could escape host galaxy and enter intracluster medium (ICM). These can confined within cluster...
Abstract High-energy cosmic rays (CRs) can be accelerated in the relativistic jets of active galactic nuclei (AGNs) powered by supermassive black holes. The baryon loading efficiency onto CR baryons from accreting holes is poorly constrained observations so far. In this paper, we suggest that γ -ray emission galaxy clusters used to study factor AGN jets, since CRs injected are completely confined and sufficiently interact with intracluster medium via a hadronic process, producing diffuse...
Proton-proton interaction and photo-hadronic in cosmic accelerators are the two main channels for production of ultra-high energy photons neutrinos (TeV-PeV). In this Letter, we use FWW approach to obtain from collision between UHE proton with magnetic field which could be considered as virtualphoton rest frame proton. We name $pB$ process. The threshold occurrence process is that combination Lorentz factor strength about $\gamma_p B \simeq 5\times 10^{18}$Gauss. Beyond threshold, rate loss...

Essentially, AGNs powered by gravitational energy matter falling supermassive black holes. However, conversion efficiency kinetic CRs in AGNs, which is defined as baryon loading factor $\eta_p$, not well known yet.
