Radio continuum emission and HI gas accretion in the NGC 5903/5898 compact group of early-type galaxies
Gopal-Krishna, Mukul Mhaskey, Paul J. Wiita +3
We discuss the nature of the multi-component radio continuum and HI emission associated with the nearby galaxy group comprised of two dominant ellipticals, NGC 5898 and NGC 5903, a…
