The mass and momentum outflow rates of photoionized galactic outflows [PDF]
, 2017 Galactic outflows are believed to play an important role in regulating star formation in galaxies, but estimates of the outflowing mass and momentum have historically been based on uncertain assumptions.

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.

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.

Anisotropic Galactic Outflows and Enrichment of the Intergalactic Medium. I: Monte Carlo Simulations [PDF]
, 2006 We have developed an analytical model to describe the evolution of anisotropic galactic outflows. With it, we investigate the impact of varying opening angle on galaxy formation and the evolution of the IGM.

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 ...

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 ...

Both starvation and outflows drive galaxy quenching [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Star-forming galaxies can in principle be transformed into passive systems by a multitude of processes that quench star formation, such as the halting of gas accretion (starvation) or the rapid removal of gas in AGN-driven outflows. However, it remains

Foreign direct investment, economic crisis and the European Union [PDF]
Romanian Economic Journal, 2013 This paper aims to demonstrate that, the European Union remained the most important player in the global investment market, despite the conditions of economic crisis.

Quasar Massive Ionized Outflows Traced by CIV λ1549 and [OIII]λλ4959,5007
Frontiers in Astronomy and Space Sciences, 2017 The most luminous quasars (with bolometric luminosities are ≳ 1047 erg/s) show a high prevalence of CIV λ1549 and [OIII]λλ4959,5007 emission line profiles with strong blueshifts.
