Gas accretion on to galaxies and Kelvin–Helmholtz turbulence
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACTContinued star formation over the lifetime of a galaxy suggests that gas is steadily flowing in from the circumgalactic medium. Also, cosmological simulations of large-scale structure formation imply that gas is accreted on to galaxies from the halo inside which they formed.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

THE MASS ACCRETION RATE OF GALAXY CLUSTERS: A MEASURABLE QUANTITY [PDF]
The Astrophysical Journal, 2016 ABSTRACT We explore the possibility of measuring the mass accretion rate (MAR) of galaxy clusters from their mass profiles beyond the virial radius R 200. We derive the accretion rate from the mass of a spherical shell whose inner radius is 2R 200, whose thickness changes with redshift, and whose ...

Jet–Accretion System in the Nearby mJy Radio Galaxies
The Astrophysical Journal, 2021 Abstract It is generally thought that FRII radio galaxies host thin optically thick disks, while FRIs are powered by advection-dominated accretion flows. Sources with an efficient engine are optically classified as high-excitation radio galaxies (HERGs) and those with an inefficient motor as low-excitation radio galaxies (LERGs ...

Environmental Toxicology, EarlyView.ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

Accretion and Outflow in Active Galaxies [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractI review accretion and outflow in active galactic nuclei. Accreti4on appears to occur in a series of very small-scale, chaotic events, whose gas flows have no correlation with the large-scale structure of the galaxy or with each other. The accreting gas has extremely low specific angular momentum and probably represents only a small fraction of

The mode of gas accretion on to star-forming galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 It is argued that galaxies like ours sustain their star formation by transferring gas from an extensive corona to the star-forming disc. The transfer is effected by the galactic fountain -- cool clouds that are shot up from the plane to kiloparsec heights above the plane. The Kelvin-Helmholtz instability strips gas from these clouds.

Bridging Scales: Modeling Suppressed Bondi Accretion on Black Holes and Its Impact on Galaxy Growth
The Astrophysical JournalThe accretion and feedback processes governing supermassive black hole (SMBH) growth span an enormous range of spatial scales, from the Event Horizon to the circumgalactic medium.
