Metal-enriched galactic outflows shape the mass–metallicity relationship [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The gas-phase metallicity of low-mass galaxies increases with increasing stellar mass (M*) and is nearly constant for high-mass galaxies. Theory suggests that this tight mass–metallicity relationship is shaped by galactic outflows removing metal-enriched

Emergence of a quasar outflow [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract We report the first discovery of the emergence of a high-velocity broad-line outflow in a luminous quasar, J105400.40+034801.2, at redshift z∼ 2.1. The outflow is evident in ultraviolet C iv and Si iv absorption lines with velocity shifts v∼ 26 300 km s−1 and deblended widths FWHM ∼4000 km s−1.

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.

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 ...

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

The COMPLETE Survey of Outflows in Perseus [PDF]
, 2010 We present a study on the impact of molecular outflows in the Perseus molecular cloud complex using the COMPLETE survey large-scale 12CO(1-0) and 13CO(1-0) maps.

Quenching star formation with quasar outflows launched by trapped IR radiation [PDF]
Monthly notices of the Royal Astronomical Society, 2017 We present cosmological radiation-hydrodynamic simulations, performed with the code Ramses-RT, of radiatively-driven outflows in a massive quasar host halo at $z = 6$.

Morphologies of protostellar outflows: An ALMA view [PDF]
, 2013 The formation of stars is usually accompanied by the launching of protostellar outflows. Observations with the Atacama Large Millimetre/sub-millimetre Array (ALMA) will soon revolutionalise our understanding of the morphologies and kinematics of these ...

The largely unconstrained multiphase nature of outflows in AGN host galaxies [PDF]
, 2018 Observations and simulations show that outflows in active galactic nuclei contain gas in different phases. To understand their true impact on galaxy evolution, we advocate consistent and unbiased investigation of these multiphase winds in large active ...

Widespread star formation inside galactic outflows [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Several models have predicted that stars could form inside galactic outflows and that this would be a new major mode of galaxy evolution. Observations of galactic outflows have revealed that they host large amounts of dense and clumpy molecular gas ...
