We introduce A strophysical H ybrid-K inetic simulations with the flash code ()–a new Hybrid
particle-in-cell (PIC) code developed within the framework of the multiphysics code flash …

Characterizing the thermodynamics of turbulent plasmas is key to decoding observable
signatures from astrophysical systems. In magnetohydrodynamic (MHD) turbulence, non …

A specific set of dimensionless plasma and turbulence parameters is introduced to
characterize the nature of turbulence and its dissipation in weakly collisional space and …

We argue that two prominent theories of ion heating in low-$\beta $ collisionless plasmas--
stochastic and quasi-linear heating--represent similar physical processes in turbulence with …

Aims. We investigated plasma turbulence in the context of solar wind. We concentrated on
properties of ideal second-order magneto-hydrodynamic (MHD) and Hall MHD invariants …

Minor ions in the solar corona are heated to extreme temperatures, far in excess of those of
the electrons and protons that comprise the bulk of the plasma. These highly nonthermal …

Understanding the partitioning of turbulent energy between ions and electrons in weakly
collisional plasmas is crucial for the accurate interpretation of observations and modelling of …

Panels (e) and (f) of Figure 4 of J. Squire et al.(2023) illustrate the time dependence of the
frequency spectra of density and perpendicular magnetic fluctuations, termed n () wd and …

This Thesis tackles three open problems in the study of radiatively efficient accretion flows
(REFs) around black holes in X-ray binary systems (XRBs) and active galactic nuclei (AGN) …

The means by which the turbulent cascade of energy is dissipated in the solar wind, and in
other astrophysical systems, is a major open question. It has recently been proposed that a …
