ΣSFR–M ∗ Diagram: A Valuable Galaxy Evolution Diagnostic to Complement (s)SFR–M ∗ Diagrams

open access: yesThe 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 ...

Spatially Resolved Stellar Populations of 0.3 < z < 6.0 Galaxies in WHL 0137–08 and MACS 0647+70 Clusters as Revealed by JWST: How Do Galaxies Grow and Quench over Cosmic Time?

open access: yesThe Astrophysical Journal, 2023
We study the spatially resolved stellar populations of 444 galaxies at 0.3 < z < 6.0 in two clusters (WHL 0137–08 and MACS 0647+70) and a blank field, combining imaging data from the Hubble Space Telescope and JWST to perform spatially resolved spectral ...

There was a star-forming galaxy that was quenched

open access: yes, 2022
Cluster galaxies are subject to a whole range of processes and interactions that dramatically change their properties. To shed light on these issues, we analyze the most homogeneous and complete local cluster galaxy survey to date: WINGS/OmegaWINGS, and use stellar population synthesis techniques to obtain properties such as stellar mass, stellar ages,

The Roles of Mass and Environment in the Quenching of Galaxies. II. [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract We take advantage of an analytic model of galaxy formation coupled to the merger tree of an N-body simulation to study the roles of environment and stellar mass in the quenching of galaxies. The model has been originally set in order to provide the observed evolution of the stellar mass function as well as reasonable predictions

The imprint of cosmic web quenching on central galaxies

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We investigate how cosmic web environment impacts the average properties of central galaxies in the Sloan Digital Sky Survey (SDSS). We analyse how the average specific star formation rate, stellar age, metallicity, and element abundance ratio [α/Fe] of SDSS central galaxies depend on distance from the cosmic web nodes, walls ...

A STELLAR MASS THRESHOLD FOR QUENCHING OF FIELD GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2012
We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (<0.06%) in the field. Our sample is based on the NASA-Sloan Atlas which is a re-analysis of the Sloan Digital Sky Survey Data Release 8.

The impact of quenching on galaxy profiles in the simba simulation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We study specific star formation rate (sSFR) and gas profiles of star-forming (SF) and green valley (GV) galaxies in the simba cosmological hydrodynamic simulation. SF galaxy half-light radii (Rhalf) at z = 0 and their evolution (∝(1 + z)−0.78) agree with observations.

Photometric Objects Around Cosmic Webs (PAC). VII. Disentangling Mass and Environment Quenching with the Aid of Galaxy–Halo Connection in Simulations

open access: yesThe Astrophysical Journal
Star formation quenching in galaxies plays a crucial role in galaxy evolution and is believed to be driven primarily by galaxy mass and environment.
