Galactic Winds [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
In the sequel we will be discussing that - apart from all other halo flows - it is highly probable that our Galaxy has a systematic mass loss; most other galaxies should behave in a similar way. This mass loss should occur in the form of a supersonic galactic wind provided the intergalactic pressure is low enough.

What Are the Radial Distributions of Density, Outflow Rates, and Cloud Structures in the M82 Wind?

open access: yesThe Astrophysical Journal, 2023
Galactic winds play essential roles in the evolution of galaxies through the feedback they provide. Despite intensive studies of winds, the radial distributions of their properties and feedback are rarely observable. Here we present such measurements for

Galactic winds and the Lyα forest [PDF]

open access: yesMonthly 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%.

CLASSY. VI. The Density, Structure, and Size of Absorption-line Outflows in Starburst Galaxies

open access: yesThe Astrophysical Journal, 2023
Galaxy formation and evolution are regulated by the feedback from galactic winds. Absorption lines provide the most widely available probe of winds.

The Structure of Multiphase Galactic Winds [PDF]

open access: yesThe Astrophysical Journal, 2022
Abstract We present a novel analytic framework to model the steady-state structure of multiphase galactic winds comprised of a hot, volume-filling component and a cold, clumpy component. We first derive general expressions for the structure of the hot phase for arbitrary mass, momentum, and energy source terms.

Resolved Velocity Profiles of Galactic Winds at Cosmic Noon

open access: yesThe Astrophysical Journal, 2023
We study the kinematics of the interstellar medium (ISM) viewed “down the barrel” in 20 gravitationally lensed galaxies during cosmic noon ( z = 1.5–3.5).

A VERSATILE FAMILY OF GALACTIC WIND MODELS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We present a versatile family of model galactic outflows including non-uniform mass and energy source distributions, a gravitational potential from an extended mass source, and radiative losses. The model easily produces steady-state wind solutions for a range of mass-loading factors, energy-loading factors, galaxy mass, and ...

Observational signatures of galactic winds powered by active galactic nuclei [PDF]

open access: yesMonthly 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 ...
