Probing satellite quenching with galaxy clustering [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Satellites within simulated massive clusters are significantly spatially correlated with each other, even when those satellites are not gravitationally bound to each other. This correlation is produced by satellites that entered their hosts relatively recently, and is undetectable for satellites that have resided in their hosts for multiple dynamical ...

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.

Quenching of satellite galaxies at the outskirts of galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We find, using cosmological simulations of galaxy clusters, that the hot X-ray emitting intra-cluster medium (ICM) enclosed within the outer accretion shock extends out to $R_{\rm shock}\sim(2 - 3) R_{\rm vir}$, where $R_{\rm vir}$ is the standard virial radius of the halo.

AGN-driven quenching of satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We explore the effect of active galactic nucleus (AGN) feedback from central galaxies on their satellites by comparing two sets of cosmological zoom-in runs of 27 haloes with masses ranging from 1012 to 1013.4$\rm {M}_{\odot}$ at z = 0, with (wAGN) and without (noAGN) AGN feedback.

THE QUENCHING TIMESCALE AND QUENCHING RATE OF GALAXIES
The Astrophysical Journal, 2016 ABSTRACT The average star formation rate (SFR) in galaxies has been declining since the redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the quenching process: the quenching timescale and the quenching rate among galaxies.

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 ABSTRACT 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) . We use a random forest classifier to identify the kinematic parameters that are most connected to galaxy quenching.

The role of quenching time in the evolution of the mass-size relation of passive galaxies from the WISP survey [PDF]
, 2016 We analyze how passive galaxies at z $\sim$ 1.5 populate the mass-size plane as a function of their stellar age, to understand if the observed size growth with time can be explained with the appearance of larger quenched galaxies at lower redshift.
