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…

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…

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…
