Multi-filament gas inflows fuelling young star-forming galaxies
WEBJul 1, 2019 · Nature Astronomy - Theoretical modelling of velocity maps of high-redshift Lyman α emitters indicates sufficient gas inflow to fuel the central galaxy’s star-formation rate and angular...
The Transition from Galaxy-wide Gas Inflow to Outflow in Quasar …
WEBAug 8, 2024 · The Transition from Galaxy-wide Gas Inflow to Outflow in Quasar Host Galaxies. Galactic-wide outflows driven by active galactic nuclei (AGNs) is a routinely invoked feedback mechanism in galaxy evolution models.
Strangulation as the primary mechanism for shutting down star ... - Nature
WEBMay 14, 2015 · Two mechanisms have been suggested, either the sudden removal of gas through outflows or stripping, or 'strangulation' in which the supply of cold gas to the galaxy is halted.
An increase in black hole activity in galaxies with ... - Nature
WEBJan 19, 2023 · Numerical simulations have suggested that misaligned structures may promote the inflow of gas to the nucleus of the galaxy and the accretion of gas by the central supermassive black hole.
The Transition from Galaxy-wide Gas Inflow to Outflow in Quasar …
WEBIn this study, we explore the factors behind the increase in [O III] emission with AGN ages, while simultaneously utilizing [O III] emission as an age indicator of AGNs to examine the evolution of high-speed outflow from nuclear region and galactic-scale outflows.
Bar formation as driver of gas inflows in isolated disc galaxies
WEBStellar bars are a common feature in massive disc galaxies. On a theoretical ground, the response of gas to a bar is generally thought to cause nuclear starbursts and, possibly, AGN activity once the perturbed gas reaches the central supermassive black hole.
Gas inflow and metallicity drops in star-forming galaxies
WEBFeb 11, 2016 · Gas inflow feeds galaxies with low-metallicity gas from the cosmic web, sustaining star formation across the Hubble time.
Galaxy ecosystems: gas contents, inflows and outflows
WEBApr 17, 2015 · We use a set of observational data for galaxy cold gas mass fraction and gas phase metallicity to constrain the content, inflow and outflow of gas in central galaxies hosted by haloes with masses between 10 11 and 10 12 M ⊙.
Radial Motions and Radial Gas Flows in Local Spiral Galaxies
WEBDec 23, 2021 · These studies found that the expected gas inflow radial motions in most star-forming galaxies are of the order of a few km s −1 within the inner optical disk and can reach 10–15 km s −1 in the outskirts. Predicted mass flows are of the order of a few M ⊙ yr −1, usually sufficient to sustain the star formation for long times.
