Universal non-thermal power-law distribution functions from the self-consistent evolution of collisionless electrostatic plasmas
Uddipan Banik, Amitava Bhattacharjee, Wrick Sengupta
Distribution functions of collisionless systems are known to show non-thermal power law tails. Interestingly, collisionless plasmas in various physical scenarios, (e.g., the ion po…

Relaxation of weakly collisional plasma: continuous spectra, discrete eigenmodes, and the decay of echoes
Uddipan Banik, Amitava Bhattacharjee
The relaxation of a weakly collisional plasma, which is of fundamental interest to laboratory and astrophysical plasmas, can be described by the Boltzmann-Poisson equations with th…

Magnetized compressible turbulence with a fluctuation dynamo and Reynolds numbers over a million
James R. Beattie, Christoph Federrath, Ralf S. Klessen +2
Supersonic magnetohydrodynamic (MHD) turbulence is a ubiquitous state for many astrophysical plasmas. However, even the basic statistics for this type of turbulence remains uncerta…
