Cosmological simulation of a radio synchrotron bridge between pre-merging galaxy clusters
Kosuke Nishiwaki, Gianfranco Brunetti, Franco Vazza +1
Radio bridges are diffuse synchrotron emission observed between merging galaxy clusters. Recent radio observations have reported both detections and non-detections of radio bridges…
Cold gas formation triggered by active galactic nuclei jet feedback in galaxy cluster cores
Stefano Sotira, Martin A. Bourne, Debora Sijacki +2
Extended warm and cold gas nebulae, with complex morphologies and kinematics, have been observed in the centres of cool-core galaxy clusters. Their origin within the hot intraclust…
Astrophysical constraints on the simulation hypothesis for this Universe: why it is (nearly) impossible that we live in a simulation
F. Vazza
We assess how physically realistic the ''simulation hypothesis'' for this Universe is, based on physical constraints arising from the link between information and energy, and on kn…
The quest for extragalactic magnetic fields
Franco Vazza
We review the observational and theoretical constraints on extragalactic magnetic fields across cosmic environment. In the next decade, the combination of sophisticated numerical s…
Influence of adaptive mesh refinement and the hydro solver on shear-induced mass stripping in a minor-merger scenario
W. Schmidt, J. Schulz, L. Iapichino +2
We compare two different codes for simulations of cosmological structure formation to investigate the sensitivity of hydrodynamical instabilities to numerics, in particular, the hy…
Merger and non-merger galaxy clusters in cosmological AMR simulations
Franco Vazza
Aims: We discuss the dependence of shocks, cosmic rays acceleration and turbulence on the dynamical state of the host clusters. Method: We perform cosmological simulations with the…
