Understanding the physical mechanisms that control galaxy formation is a fundamental
challenge in contemporary astrophysics. Recent advances in the field of astrophysical …

Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far.
They operate over the full extent of their galaxy hosts, from the innermost regions of galactic …

The halo of the Milky Way provides a laboratory to study the properties of the shocked hot
gas that is predicted by models of galaxy formation. There is observational evidence of …

We present a new model for the distribution of free electrons in the Galaxy, the Magellanic
Clouds, and the intergalactic medium (IGM) that can be used to estimate distances to real or …

The newly launched X-ray satellite, eROSITA, has recently revealed two gigantic bubbles
extending to~ 80° above and below the Galactic Centre. The morphology of these 'eROSITA …

The Galactic center excess (GCE) remains one of the most intriguing discoveries from the
Fermi Large Area Telescope (LAT) observations. We revisit the characteristics of the GCE by …

The TNG50 cosmological simulation produces X-ray emitting bubbles, shells, and cavities in
the circumgalactic gas above and below the stellar discs of Milky Way-and Andromeda-like …

Galaxy-scale outflows of gas, or galactic winds (GWs), driven by energy from star formation
are a pivotal mechanism for regulation of star formation in the current model of galaxy …

Abstract The Galactic Centre contains a supermassive black hole with a mass of four million
Suns within an environment that differs markedly from that of the Galactic disk. Although the …

We use hydrodynamical simulations to study the Milky Way's central molecular zone (CMZ).
The simulations include a non-equilibrium chemical network, the gas self-gravity, star …
