Ageing and dynamics of the tailed radio galaxies in Abell 2142
Ageing and dynamics of the tailed radio galaxies in Abell 2142
Context. Tailed radio galaxies are shaped by ram pressure owing to the high-velocity motion of their host through the intracluster medium (ICM). Recent works have reported on the increasing complexity of the phenomenology of tailed galaxies, with departures from theoretical ageing models and evidence of re-energising mechanisms, which are yet …
