A galactic outflow traced by its extended Mg II emission out to a∼ 30 kpc radius in the Hubble Ultra Deep Field with MUSE

I Pessa, L Wisotzki, T Urrutia, J Pharo… - Astronomy & …, 2024 - aanda.org
We report the discovery of a rare Mg IIλλ2796, 2803 doublet emission halo around a star-
forming galaxy with log (M⋆/M⊙)= 10.3±0.3 at z= 0.737 in deep (9.94 h) VLT/MUSE data …

Capturing Turbulence with Numerical Dissipation: a Simple Dynamical Model for Unresolved Turbulence in Hydrodynamic Simulations

VA Semenov - arxiv preprint arxiv:2410.23339, 2024 - arxiv.org
Modeling unresolved turbulence in astrophysical gasdynamic simulations can improve the

Detecting the Effect of Nonthermal Sources on the Warm-hot Galactic Halo

S Das - The Astrophysical Journal Letters, 2024 - iopscience.iop.org
We report the first detection of nonthermal broadening of O vii lines in the warm-hot≈ 10 6 K
circumgalactic medium of the Milky Way. We use z= 0 absorption of O vii Kα, O vii Kβ, and O …
