Beyond Maxwell-Boltzmann: Transport in Quasiequilibrium Plasmas
Kamel Ourabah
Space plasmas are generally characterized by non-Maxwellian distributions with suprathermal populations, as routinely revealed by in situ observations. Such departures from standar…

Jeans analysis in modified gravity: A general formulation
Ryan Khaled, Kamel Ourabah
We study the Jeans instability of a self-gravitating fluid in the context of alternative gravitational theories. Our formulation accommodates arbitrary corrections to the Newtonian…

Reaction Rates in Quasiequilibrium States
Kamel Ourabah
Non-Maxwellian distributions are commonly observed across a wide range of systems and scales. While direct observations provide the strongest evidence for these distributions, they…
