Spurred by rich, multiwavelength observations and enabled by new simulations, ranging
from cosmological to subparsec scales, the past decade has seen major theoretical …

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

The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite
began surveying the sky in December 2019, with the aim of producing all-sky X-ray source …

We analyse the physical properties of gas in the circumgalactic medium (CGM) of 132 Milky
Way (MW)-like galaxies at z= 0 from the cosmological magneto-hydrodynamical simulation …

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 …

Abstract The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project led by
the Italian National Institute for Astrophysics (INAF) is developing and will deploy at the …

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 …

We present a suite of models of the coherent magnetic field of the Galaxy based on new
divergence-free parametric functions describing the global structure of the field. The model …

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 …

We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial
distribution of the hot circumgalactic medium (CGM,[0.1–1] R 200c) through its emission …
