Comparing Star Formation Histories and Evolutionary Pathways of Post-starburst and E+A Galaxies in TNG50 and SDSS-IV MaNGA

The Astrophysical Journal
E+A galaxies represent a class of recently quenched objects, with spectra that show evidence of a previous substantial starburst and strong Balmer absorption lines indicative of A-type stellar populations.

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

Starburst Galaxies in Their Last Billion Years: An Hδ Absorption Line Selected Sample

The Astrophysical Journal
In this paper, we focus on the study of starburst galaxies in their final billion years. Our galaxy selection is based solely on the presence of the H δ absorption line, which permits the later evolution of starburst galaxies to be traced, coinciding ...

Massive post-starburst galaxies at z > 1 are compact proto-spheroids [PDF]

, 2017
We investigate the relationship between the quenching of star formation and the structural transformation of massive galaxies, using a large sample of photometrically-selected poststarburst galaxies in the UKIDSS UDS field.

The Size–Mass Relation of Post-starburst Galaxies in the Local Universe

The Astrophysical Journal, 2022
Abstract We present a study of the size–mass relation for local post-starburst (PSB) galaxies at z ≲ 0.33 selected from the Sloan Digital Sky Survey Data Release 8. We find that PSB galaxies with stellar mass (M *) at 109 M ☉ < M * < 1012 M
