Critical magnetic Reynolds number of the weakly-collisional turbulent dynamo in supersonic plasmas
Weakly-collisional plasmas are found in several turbulent astrophysical environments, such as the Intra-galaxy-cluster medium (ICM) and the solar wind, where magnetic fields can be amplified by the turbulent dynamo. The onset of dynamo action is determined by the critical magnetic Reynolds number, ${\rm Rm}_{\rm crit}$...
