Quenching of Star Formation [PDF]

, 2008
In the last decade we have seen an enormous increase in the size and quality of spectroscopic galaxy surveys, both at low and high redshift. New statistical techniques to analyse large portions of galaxy spectra are now finding favour over traditional ...

Caught in the Act of Quenching? -- A Population of Post-Starburst Ultra-Diffuse Galaxies

The Open Journal of Astrophysics
We report the discovery of post-starburst ultra-diffuse galaxies (UDGs), identified through spectroscopic analysis with KCWI at the Keck II Telescope. Our analysis is based on a sample of 44 candidate UDGs selected from the Systematically Measuring Ultra-

Star Formation and Selective Dust Extinction in Luminous Starburst Galaxies [PDF]

, 2000
We investigate the star formation and dust extinction properties of very luminous infrared galaxies whose spectra display a strong Hdelta line in absorption and a moderate [OII] emission (e[a] spectrum). This spectral combination has been suggested to be

SQuIGG E: Buried Star Formation Cannot Explain the Rapidly Fading CO(2–1) Luminosity in Massive, z ∼ 0.7 Post-starburst Galaxies

The Astronomical Journal
Observational and theoretical studies have long held that rapid gas consumption in starbursts is responsible for the formation of the most massive quiescent galaxies at high redshift.

Star Formation in QSO Host Galaxies

, 2006
Many of the conditions that are necessary for starbursts appear to be important in the triggering of QSOs. However, it is still debatable whether starbursts are ubiquitously present in galaxies harboring QSOs.

An Atlas of Color-selected Quiescent Galaxies at z > 3 in Public JWST Fields

The Astrophysical Journal, 2023
We present the results of a systematic search for candidate quiescent galaxies in the distant universe in 11 JWST fields with publicly available observations collected during the first 3 months of operations and covering an effective sky area of ∼145 ...

On the Origin of [OII] Emission in Red Sequence and Post-starburst Galaxies

, 2005
We investigate the emission-line properties of galaxies with red rest-frame colors using spectra from SDSS DR4. Emission lines are detected in more than half of the red galaxies.

Velocity Segregation and Systematic Biases In Velocity Dispersion Estimates With the SPT-GMOS Spectroscopic Survey [PDF]

, 2017
The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocity distributions of different populations of galaxies within 89 Sunyaev Zel'

Reconstructing the Assembly of Massive Galaxies. II. Galaxies Develop Massive and Dense Stellar Cores as They Evolve and Head toward Quiescence at Cosmic Noon

The Astrophysical Journal, 2023
We use the spectral energy distribution fitting code Prospector to reconstruct the nonparametric star formation history (SFH) of massive ( $\mathrm{log}{M}_{* }\gt 10.3$ ) star-forming galaxies (SFGs) and quiescent galaxies (QGs) at redshift z _obs ∼ 2 ...
