Cosmic ray heating of cold streams: Implications for the gas supply and growth of massive galaxies

Recent observations have demonstrated the presence of cosmic rays (CRs) in cosmic-web filaments.

Recent observations have demonstrated the presence of cosmic rays (CRs) in cosmic-web filaments. Cold streams supply gas inflows from these filaments into massive galaxies during the cosmic noon. As these streams are expected to be magnetised, external cosmic-web CRs may become…
