Short summary
Electron holes have been reported in space plasmas along with suprathermal plasmas far from Maxwellian equilibrium. In particular, electron distributions with elongated suprathermal distributions (kappa distributions) are of current interest for space plasmas. This work considers regularized kappa distributions, which are well beyond the Maxwellian equilibrium and show a harder suprathermal electron population.
