The solar wind is a magnetized plasma and as such exhibits collective plasma behavior
associated with its characteristic spatial and temporal scales. The characteristic length …

We review the present theoretical and numerical understanding of magnetic field
amplification in cosmic large-scale structure, on length scales of galaxy clusters and beyond …

We present and study a large suite of high-resolution cosmological zoom-in simulations,
using the FIRE-2 treatment of mechanical and radiative feedback from massive stars …

These lecture notes are based on a tutorial given in 2017 at a plasma physics winter school
in Les Houches. Their aim is to provide a self-contained graduate-student level introduction …

We find that clouds of optically thin, pressure-confined gas are prone to fragmentation as
they cool below∼ 106 K. This fragmentation follows the lengthscale∼ cst cool, ultimately …

We present results from three-dimensional hybrid-kinetic simulations of Alfvénic turbulence
in a high-β, collisionless plasma. The key feature of such turbulence is the interplay between …

The Event Horizon Telescope (EHT) has opened a new window on supermassive black
holes. With the advent of millimeter and submillimeter very long baseline interferometry …

Axion-like particles (ALPs) and photons can quantum mechanically interconvert when
propagating through magnetic fields, and ALP-photon conversion may induce oscillatory …

Star formation and supermassive black hole growth in galaxies appear to be self-limiting.
The mechanisms for self-regulation are known as feedback. Cosmic rays, the relativistic …

In a companion paper, we present the first spatially resolved polarized image of Sagittarius
A* on event horizon scales, captured using the Event Horizon Telescope, a global very long …
