Annual Review of Astronomy and Astrophysics, 2005 ▪ Abstract Galactic winds are the primary mechanism by which energy and metals are recycled in galaxies and are deposited into the intergalactic medium. New observations are revealing the ubiquity of this process, particularly at high redshift. We describe the physics behind these winds, discuss the observational evidence for them in nearby star ...

A Review of the Theory of Galactic Winds Driven by Stellar Feedback
Galaxies, 2018 Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals ...

How supernovae launch galactic winds? [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2017 Abstract We use idealized three-dimensional hydrodynamic simulations of global galactic discs to study the launching of galactic winds by supernovae (SNe). The simulations resolve the cooling radii of the majority of supernova remnants (SNRs) and thus self-consistently capture how SNe drive galactic winds.

Observational signatures of galactic winds powered by active galactic nuclei [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We predict the observational signatures of galaxy scale outflows powered by active galactic nuclei (AGN). Most of the emission is produced by the forward shock driven into the ambient interstellar medium (ISM) rather than by the reverse shock. AGN powered galactic winds with energetics suggested by phenomenological feedback arguments should produce ...

Magnetic field seeding by galactic winds [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 The origin of intergalactic magnetic fields is still a mystery and several scenarios have been proposed so far: among them, primordial phase transitions, structure formation shocks and galactic outflows. In this work we investigate how efficiently galactic winds can provide an intense and widespread "seed" magnetisation. This may be used to explain the

Cosmic ray driven galactic winds [PDF]
International Journal of Modern Physics D, 2020 Galactic winds constitute a primary feedback process in the ecology and evolution of galaxies. They are ubiquitously observed and exhibit a rich phenomenology, whose origin is actively investigated both theoretically and observationally. Cosmic rays have been widely recognized as a possible driving agent of galactic winds, especially in Milky–Way like

GALACTIC WINDS IN IRREGULAR STARBURST GALAXIES [PDF]
, 2001 In this paper we present some results concerning the study of the development of galactic winds in blue compact galaxies. In particular, we model a situation very similar to that of the galaxy IZw18, the most metal poor and unevolved galaxy known locally.

CONDITIONS FOR SUPERNOVAE-DRIVEN GALACTIC WINDS [PDF]
The Astrophysical Journal, 2013 We point out that the commonly assumed condition for galactic outflows, that supernovae (SNe) heating is efficient in the central regions of starburst galaxies, suffers from invalid assumptions. We show that a large filling factor of hot ($\ge 10^6$ K) gas is difficult to achieve through SNe heating, irrespective of the initial gas temperature and ...

Clustered supernovae drive powerful galactic winds after superbubble breakout
Monthly Notices of the Royal Astronomical Society, 2018 We use three-dimensional hydrodynamic simulations of vertically stratified patches of galactic discs to study how the spatio-temporal clustering of supernovae (SNe) enhances the power of galactic winds.

A Review of Recent Observations of Galactic Winds Driven by Star Formation
Galaxies, 2018 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 evolution.
