Environmental Quenching of Low-Mass Field Galaxies [PDF]
Mon Not R Astron Soc, 2018 In the local Universe, there is a strong division in the star-forming properties of low-mass galaxies, with star formation largely ubiquitous amongst the field population while satellite systems are predominantly quenched.

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

Quenching of Massive Disk Galaxies in the IllustrisTNG Simulation
The Astrophysical Journal, 2022 A rare population of massive disk galaxies have been found to invade the red sequence dominated by early-type galaxies. The formation and origins of these red/quenched massive disk galaxies have recently gained great interest.

DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at z ∼ 1
The Astrophysical Journal Letters, 2023 We utilize ∼17,000 bright luminous red galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep (∼2.5 hr galaxy ^−1 exposure time) spectra to characterize the contribution of recently

The Astrophysical Journal, 2023 Recent observations have reignited interest in a population of dwarf galaxies that are large and diffuse for their mass, often called ultra-diffuse galaxies (UDGs).

Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups
The Astrophysical Journal, 2023 We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching in 0.2 < z < 0.8 groups.

Active Galactic Nucleus Quenching in Simulated Dwarf Galaxies
The Astrophysical Journal, 2023 We examine the quenching characteristics of 328 isolated dwarf galaxies $\left({10}^{8}\lt {M}_{\mathrm{star}}/{M}_{\odot }\lt {10}^{10}\right)$ within the Romulus25 cosmological hydrodynamic simulation.

Galactic conformity measured in semi-analytic models [PDF]
, 2017 We study the correlation between the specific star formation rate of central galaxies and neighbour galaxies, also known as 'galactic conformity', out to 20 Mpc/h using three semi-analytic models (SAMs, one from L-GALAXIES and other two from GALFORM ...

The Astrophysical Journal Letters, 2023 How passive galaxies form, and the physical mechanisms which prevent star formation over long timescales, are some of the most outstanding questions in understanding galaxy evolution.

Stellar Mass and Velocity Functions of Galaxies: Backward evolution and the fate of Milky Way siblings [PDF]
, 2010 We attempt in this paper to check the consistency of the observed Stellar Mass Function (SMF), SFR functions and the cosmic star formation rate density with simple backward evolutionary models. Starting from observed SMF for star-forming galaxies, we use
