Gas Accretion and Star-Formation Rates with IFUs and Background Quasars,show that their gas reservoir ought to be depleted in 0.5–2 Gyr. Thus, SFGs are thought to be fed by the continuous accretion of intergalactic gas in order to sustain their star-formation activity. However, direct observational evidence for this accretion phenomenon has been elusive. Theoretically,

Accretion has long been seen around the

Decomposition of Data Matrices by Factorse II has provided evidence for ongoing gas accretion onto > 5% of luminous, star-forming galaxies at . ∼ 0. 5–1. We then discuss the potentially ground-breaking benefits of future efforts to improve the spectral resolution of such studies, and to leverage spatially resolved spectroscopy for new cons

Wolfgang Karl Härdle,Léopold SimarLSs and LLSs so far studied are located in the CGM of galaxies with projected distances . 100–200 kpc. Regardless of the exact origin of the low-metallicity pLLSs/LLSs, there is a significant mass of cool, dense, low-metallicity gas in the CGM that may be available as fuel for continuing star format

What Is Natural Language Processing?,rgers are an overall subdominant mechanism for delivering fresh gas to galaxies, but they trigger radial flows of previously accreted gas that flatten radial gas-phase metallicity gradients and temporarily suppress central metallicities. Radial gradients are generically expected to be steep at early

We discuss the implications of these simulations, reviewing a number of recent developments in the literature, and suggest a revision to the canonical model as it relates to the expected angular momentum content of gaseous halos around galaxies.
