The Astrophysical Journal, 2023 The origin of cosmic rays (CRs) above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a nonrotating, expanding flux tube with a changing speed and cross-sectional area.

Galactic winds and the Lyα forest [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We study the effect of galactic outflows on the Lya forest. The winds are modelled as fully ionised spherical bubbles centered around galactic haloes. The observed flux probability distribution and flux power spectrum limit the volume filling factor of bubbles to be less than 10%.

Dust entrainment in galactic winds [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Winds driven by stellar feedback are an essential part of the galactic ecosystem and are the main mechanism through which low-mass galaxies regulate their star formation. These winds are generally observed to be multiphase with detections of entrained neutral and molecular gas.

Type Ia supernova-driven Galactic bulge wind [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 Stellar feedback in galactic bulges plays an essential role in shaping the evolution of galaxies. To quantify this role and facilitate comparisons with X-ray observations, we conduct 3D hydrodynamical simulations with the adaptive mesh refinement code, FLASH, to investigate the physical properties of hot gas inside a galactic bulge, similar to that of ...

AGN Jet Mass Loading and Truncation by Stellar Winds [PDF]
, 2006 Active Galactic Nuclei can produce extremely powerful jets. While tightly collimated, the scale of these jets and the stellar density at galactic centers implies that there will be many jet/star interactions, which can mass-load the jet through stellar ...

The Discovery of 1000 km/s Outflows in Massive Post-starburst Galaxies at z=0.6 [PDF]
, 2007 Numerical simulations suggest that active galactic nuclei (AGNs) play an important role in the formation of early-type galaxies by expelling gas and dust in powerful galactic winds and quenching star formation.

Metal-Enhanced Galactic Winds [PDF]
Symposium - International Astronomical Union, 1987 Constraints on supernova-driven galactic winds from elliptical galaxies at the epoch of star formation are investigated. The occurrence of mass loss is found to depend critically on the supernova rate in the case of dwarf galaxies, while the depth of the potential well is the most important constraint for giant ellipticals.

Stellar Mass Loss-Driven Wind Models of Elliptical Galaxies?
, 1994 Recent claims in the literature (Bressan, Chiosi & Fagotto 1994) that the epoch describing the onset of galactic winds in spheroidal star systems has been severely overestimated in the past, due to the neglect of energy deposited in the interstellar ...

Powering galactic superwinds with small-scale AGN winds [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We present a new implementation for active galactic nucleus (AGN) feedback through small-scale, ultrafast winds in the moving-mesh hydrodynamic code arepo. The wind is injected by prescribing mass, momentum, and energy fluxes across a spherical boundary centred on a supermassive black hole according to available constraints for ...
