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 ...

How supernovae launch galactic winds? [PDF]

open access: yesMonthly 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.

GALACTIC WINDS IN IRREGULAR STARBURST GALAXIES [PDF]

open access: yes, 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.

An Analytic Model of Galactic Winds and Mass Outflows [PDF]

open access: yesChinese Journal of Astronomy and Astrophysics, 2005
Galactic winds and mass outflows are observed both in nearby starburst galaxies and in high-redshift star-forming galaxies. We develop a simple analytic model to understand the observed superwind phenomenon with a discussion of the model uncertainties. Our model is built upon the model of McKee & Ostriker for the interstellar medium.

Simulating supernova feedback in galaxy disks [PDF]

open access: yes, 2012
In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

A Global Inventory of Feedback

open access: yesGalaxies, 2023
Feedback from both supermassive black holes and massive stars plays a fundamental role in the evolution of galaxies and the inter-galactic medium. In this paper, we use available data to estimate the total amount of kinetic energy and momentum created ...

Physical Conditions of the Ionized Superwind in NGC 253 with VLT/MUSE

open access: yesThe Astrophysical Journal
We present an analysis of the H α -emitting ionized gas in the warm phase of the NGC 253 outflow using integral field spectroscopy from the Multi Unit Spectroscopic Explorer.

Galactic Winds and the Missing Baryons [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2004
AbstractGalaxy-scale winds are poised to solve a number of ailments in modern cosmology. However, we know little about trends of wind properties with host galaxy properties. In an attempt to quantify the impact of galactic winds on their host galaxies and the environment, we are conducting a systematic survey of star-forming and active galaxies at z ...

The Impact of Supermassive Black Holes on Exoplanet Habitability. I. Spanning the Natural Mass Range

open access: yesThe Astrophysical Journal
While the influence of supermassive black hole (SMBH) activity on habitability has garnered attention, the specific effects of active galactic nucleus (AGN) winds, particularly ultrafast outflows (UFOs), on planetary atmospheres remain largely unexplored.
