What drives galaxy quenching? A deep connection between galaxy kinematics and quenching in the local Universe [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 We develop a 2D inclined rotating disc model, which we apply to the stellar velocity maps of 1862 galaxies taken from the MaNGA survey (SDSS public Data Release 15).

Rapid Quenching of Galaxies at Cosmic Noon
The Astrophysical Journal, 2023 The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and what physical mechanisms are involved.

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

Probing Satellite Quenching With Galaxy Clustering [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Satellites within simulated massive clusters are significantly spatially correlated with each other, even when those satellites are not gravitationally bound to each other.

The First Quenched Galaxies: When and How?
The Astrophysical Journal LettersMany quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...

THE MASS DEPENDENCE OF DWARF SATELLITE GALAXY QUENCHING [PDF]
The Astrophysical Journal, 2014 We combine observations of the Local Group with data from the NASA-Sloan Atlas to show the variation in the quenched fraction of satellite galaxies from low-mass dwarf spheroidals and dwarf irregulars to more massive dwarfs similar to the Magellanic ...

The impact of quenching on galaxy profiles in the simba simulation [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 We study specific star formation rate (sSFR) and gas profiles of star forming and green valley galaxies in the Simba cosmological hydrodynamic simulation. Star-forming galaxy half-light radii ($R_{\rm half}$) at $z=0$ and their evolution ($\propto(1+z)^{-

Star formation quenching in massive galaxies [PDF]
Nature Astronomy, 2018 Understanding how and why star formation turns off in massive galaxies is a major challenge for studies of galaxy evolution. Many theoretical explanations have been proposed, but a definitive consensus is yet to be reached.

Galaxy Zoo: Major Galaxy Mergers Are Not a Significant Quenching Pathway* [PDF]
The Astrophysical Journal, 2017 Abstract We use stellar mass functions to study the properties and the significance of quenching through major galaxy mergers. In addition to SDSS DR7 and Galaxy Zoo 1 data, we use samples of visually selected major galaxy mergers and post-merger galaxies.

A dichotomy in satellite quenching around L* galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We examine the star formation properties of bright (~0.1 L*) satellites around isolated ~L* hosts in the local Universe using spectroscopically confirmed systems in the Sloan Digital Sky Survey DR7. Our selection method is carefully designed with the aid of N-body simulations to avoid groups and clusters.
