The Roles of Mass and Environment in the Quenching of Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We study the roles of stellar mass and environment in quenching the star formation activity of a large set of simulated galaxies by taking advantage of an analytic model coupled to the merger tree extracted from an N-body simulation. The analytic model has been set to match the evolution of the global stellar mass function since

ΣSFR–M ∗ Diagram: A Valuable Galaxy Evolution Diagnostic to Complement (s)SFR–M ∗ Diagrams
The Astrophysical Journal, 2023 The specific star formation rate (sSFR) is commonly used to describe the level of galaxy star formation (SF) and to select quenched galaxies. However, since it is a relative measure of the young-to-old population, an ambiguity in its interpretation may ...

Relight the Candle: What happens to High Redshift Massive Quenched Galaxies [PDF]
arXiv, 2023 A puzzling population of extremely massive quiescent galaxies at redshifts beyond z=3 has recently been revealed by JWST and ALMA, some of them with stellar ages that show their quenching times to be as high as z=6, while their stellar masses are already above 5e10Msun. These extremely massive yet quenched galaxies challenge our understanding of galaxy

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 Astrophysical Journal, 2023 We examine the wavelength dependence of radial light profiles based on Sérsic index n measurements of 1067 galaxies with M _* ≥ 10 ^9.5 M _⊙ and in the redshift range 0.5 < z < 3. The sample and rest-frame optical light profiles are drawn from the Cosmic

Quenching star formation in cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 In order to understand the processes that quench star formation within rich clusters, we construct a library of subhalo orbits drawn from $ $CDM cosmological N-body simulations of four rich clusters. The orbits are combined with models of star formation followed by quenching in the cluster environment.

From Brad to worse: Rule‐consequentialism and undesirable futures
Ratio, Volume 35, Issue 4, Page 275-288, December 2022., 2022 Abstract This paper asks how rule‐consequentialism might adapt to very adverse futures, and whether moderate liberal consequentialism can survive into broken futures and/or futures where humanity faces imminent extinction. The paper first recaps the recent history of rule‐consequentialist procreative ethics.

Quenching Timescales in the IllustrisTNG Simulation [PDF]
, 2022 The timescales for galaxy quenching offer clues to its underlying physical drivers. We investigate central galaxy quenching timescales in the IllustrisTNG 100-1 simulation, their evolution over time, and the pre-quenching properties of galaxies that predict their quenching timescales.

Revealing impacts of stellar mass and environment on galaxy quenching [PDF]
A&A 666, A141 (2022), 2022 Galaxy quenching is a critical step in galaxy evolution. In this work, we present a statistical study of galaxy quenching in 17 cluster candidates at 0.5

Overconsumption, outflows and the quenching of satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract The baryon cycle of galaxies is a dynamic process involving the intake, consumption and ejection of vast quantities of gas. In contrast, the conventional picture of satellite galaxies has them methodically turning a large gas reservoir into stars until this reservoir is forcibly removed due to external ram pressure. This picture
