Reviving Fossil Radio Plasma in Clusters of Galaxies by Adiabatic Compression in Environmental Shock Waves
Torsten A. Ensslin, Gopal-Krishna
We give for a plasma with a history of several expansion and contraction phases an analytical model of the evolution of a contained relativistic electron population under synchrotr…
On the Origin of the Fanaroff-Riley Dichotomy
Gopal-Krishna, Paul J. Wiita
A small fraction of double radio sources show a peculiar and striking hybrid morphology; they have a distinctly FR I structure on one side of the nucleus, and a FR II structure on…
Extragalactic radio sources with hybrid morphology: implications for the Fanaroff-Riley dichotomy
Gopal-Krishna, Paul J. Wiita
We provide observational and theoretical perspectives on the currently much debated issue of the Fanaroff-Riley (FR) morphological dichotomy of extragalactic radio sources. In this…
Radio Jet-blown Neutral Hydrogen Supershells in Spiral Galaxies?
Gopal-Krishna, Judith A. Irwin
Taking a clue from the pair of HI supershells found in the Scd galaxy NGC 3556 (M 108), we propose a new mechanism for the origin of HI supershells in gas-rich massive galaxies. In…
