Production of Cool Gas in Thermally Driven Outflows [PDF]
Astrophysical Journal, 2018 Galactic outflows commonly contain multiphase gas, and its physical origin requires explanation. Using the Cholla Galactic OutfLow Simulations suite of high-resolution isolated galaxy models, we demonstrate the viability of rapid radiative cooling as a ...

Ionized Gas Outflows from the MAGNUM Survey: NGC 1365 and NGC 4945
Frontiers in Astronomy and Space Sciences, 2017 AGN feedback, acting through strong outflows accelerated in the nuclear region of AGN hosts, is invoked as a key ingredient for galaxy evolution by many models to explain the observed BH-galaxy scaling relations.

AGN Feedback and Its Quenching Efficiency
Frontiers in Astronomy and Space Sciences, 2017 In the last decade, observations have accumulated on gas outflows in galaxies, and in particular massive molecular ones. The mass outflow rate is estimated between 1 and 5 times the star formation rate. For the highest maximal velocities, they are driven

Direct Evidence for Termination of Obscured Star Formation by Radiatively Driven Outflows in Reddened QSOs [PDF]
, 2011 We present optical to far-infrared photometry of 31 reddened QSOs that show evidence for radiatively driven outflows originating from AGN in their rest-frame UV spectra.

Evidence that 50% of BALQSO Outflows Are Situated at Least 100 pc from the Central Source [PDF]
, 2018 The most robust way for determining the distance of quasar absorption outflows is the use of troughs from ionic excited states. The column density ratio between the excited and resonance states yields the outflow number density. Combined with a knowledge

MAGNUM survey: A MUSE-Chandra resolved view on ionized outflows and photoionization in the Seyfert galaxy NGC1365 [PDF]
Astronomy & Astrophysics, 2018 Context. Ionized outflows, revealed by broad asymmetric wings of the [O III] λ5007 line, are commonly observed in active galactic nuclei (AGN) but the low intrinsic spatial resolution of the observations has generally prevented a detailed ...

MaGICC discs: matching observed galaxy relationships over a wide stellar mass range [PDF]
, 2012 We use the same physical model to simulate four galaxies that match the relation between stellar and total mass, over a mass range that includes the vast majority of disc galaxies.

Modeling of the Wind/Disk Outflow from Be Stars
Universe, 2021 The objective of this work is to reproduce the formation of the fast polar wind and viscous disk outflow from Be stars in a unified physical picture. Numerical modeling of the plasma outflow from fast rotating stars was performed taking into account the ...

Kiloparsec Scale Properties of Star Formation Driven Outflows at z ∼ 2.3 in the SINS/zC-SINF AO Survey [PDF]
Astrophysical Journal, 2018 We investigate the relationship between star formation activity and outflow properties on kiloparsec scales in a sample of 28 star-forming galaxies at z ∼ 2–2.6, using adaptive optics assisted integral field observations from SINFONI on the Very Large ...

Radio Continuum Spectra of Planetary Nebulae
Galaxies, 2018 Radio continuum emission of planetary nebulae is a rich source of information about their structure and physical parameters. Although radio emission is well studied, planetary nebulae show higher spectral indices than expected for homogeneous sphere.
