Theory of Star Formation
TL;DR: In this paper, an overall theoretical framework and the observations that motivate it are outlined, outlining the key dynamical processes involved in star formation, including turbulence, magnetic fields, and self-gravity.
Journal ArticleDOI
Dynamo action by differential rotation in a stably stratified stellar interior
TL;DR: In this article, a dynamo model is developed from these ingredients, and applied to the problem of angular momentum transport in stellar interiors, which is found to be more effective in transporting angular momentum than the known hydrodynamic mechanisms.
Journal ArticleDOI
Extragalactic magnetic fields
TL;DR: In this paper, the observational methods for detecting and measuring extragalactic magnetic fields are discussed, along with some new indirect methods which could be used for inferring field strengths at large redshifts which are otherwise beyond the reach of direct measurement.

General relativistic magnetohydrodynamic simulations of magnetically choked accretion flows around black holes
TL;DR: In this paper, the authors studied global general relativistic magnetohydrodynamic (MHD) simulations of radially extended and thick (height H to cylindrical radius R ratio of |H/R| {approx} 0.2-1) accretion flows around BHs with various dimensionless spins (a/M, with BH mass M) and with initially toroidally-dominated ({phi}-directed) and poloidallydominated (R-z directed) magnetic fields.

Rayleigh–Taylor and Richtmyer-Meshkov instability induced flow, turbulence, and mixing. II
TL;DR: In this article, Zhou et al. presented the initial condition dependence of Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) mixing layers, and introduced parameters that are used to evaluate the level of mixedness and mixed mass within the layers.

TL;DR: In this article, the high-energy diffuse gamma-ray emission from the Galactic plane, |b| ≤ 10°, was studied using observations from the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma-ray Observatory, and the spatial distribution of the diffuse emission was determined for four broad energy ranges after removing the contribution from point sources detected with greater than 5 σ significance.
