High Velocity Neutral Gas in the Fermi Bubbles: New Kinematic Limits and Spatial Structure
Felix J. Lockman, Enrico M. Di Teodoro, Savannah Cary +1
We have detected hundreds of neutral clouds entrained in the Milky Way's nuclear wind using HI data from new surveys made with the Green Bank Telescope that cover about 500 sq-degr…
Megaparsec-Scale Neutral Hydrogen Flows in the Neighborhood of Hickson Compact Group 100
Qingzheng Yu, Taotao Fang, Enrico M. Di Teodoro +2
The evolution of galaxies is strongly influenced by their ability to exchange gas with their surroundings, yet direct observational constraints on these processes remain scarce. Us…
Simulating winds in the Galactic centre: I. Supernova-driven multiphase outflows and HI cloud acceleration
Nicolas Peschken, Enrico M. Di Teodoro, Michał Hanasz +5
The centre of the Milky Way (MW) hosts powerful multiphase outflows, as evidenced by the Fermi and eROSITA bubbles, and by cold atomic hydrogen (HI) gas clouds detected up to a few…
The Baryonic Faber-Jackson Relation and Fundamental Plane of Galaxy Groups, Elliptical Galaxies, and Dwarf Galaxies
Yong Tian, Federico Lelli, Marcel S. Pawlowski +7
The baryonic Faber-Jackson relation (BFJR) links the baryonic mass of pressure-supported systems to their mean velocity dispersion. For elliptical galaxies, the BFJR is thought to…
Turbulence statistics of HI clouds entrained in the Milky Way's nuclear wind
Isabella A. Gerrard, Karlie A. Noon, Christoph Federrath +3
The interstellar medium (ISM) is ubiquitously turbulent across many physically distinct environments within the Galaxy. Turbulence is key in controlling the structure and dynamics…
Feedback and ionized gas outflows in four low-radio power AGN at z 0.15
L. Ulivi, G. Venturi, G. Cresci +19
An increasing number of observations and simulations suggests that low-power (<10 erg s) jets may be a significant channel of feedback produced by active galactic nuc…
