DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at z ∼ 1

open access: yesThe 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

E+A Galaxies in and Around Nearby Rich Clusters of Galaxies

open access: yesResearch Notes of the AAS, 2021
Abstract We have spectroscopically identified 600 new E+A galaxies and candidates across 16 fields totaling roughly 480 square degrees in the Sloan Digital Sky Survey. E+A galaxies are post-starburst systems that have undergone a significant burst of star formation within the past 1–2 Gyr and are now fully quenched. They comprise a small

Five E+A (post-starburst) galaxies as Brightest Cluster Galaxies [PDF]

open access: yesScience China Physics, Mechanics and Astronomy, 2012
Brightest Cluster Galaxies (BCGs) are mostly elliptical galaxies and very rarely have prominent star formations. We found that five out of 8,812 BCGs are E+A (i.e., post-starburst) galaxies, having an Hδ absorption line with an equivalent width >2.5 A and no distinct emission lines in [O II] and Hα −.

Merger Signatures are Common, but not Universal, in Massive, Recently Quenched Galaxies at z ∼ 0.7

open access: yesThe Astrophysical Journal, 2023
We present visual classifications of merger-induced tidal disturbances in 143 M _* ∼ 10 ^11 M _⊙ post-starburst galaxies at z ∼ 0.7 identified in the $\mathrm{SQuIGG}\vec{L}{\rm{E}}$ Sample.

Radial and 2D colour properties of E+A galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2005
We investigated the radial colour gradient and two-dimensional (2D) colour properties of 22 E+A galaxies with 5.5 < Hdelta equivalent width(EW) < 8.5 and 49 normal early-type galaxies as a control sample at a redshift of <0.2 in the Second Data Release of the Sloan Digital Sky Survey. We found that a substantial number of E+A galaxies exhibit

“E+A” Galaxies: Environment and Evolution [PDF]

open access: yesSymposium - International Astronomical Union, 1999
One important approach to the study of galaxy evolution is to identify those galaxies whose spectral and/or morphological characteristics suggest that they are in transition. For example, “E+A” galaxies, which have strong Balmer absorption lines and no significant [OII] emission, are generally interpreted as post-starburst galaxies in which the star ...

Fourteen E+A Galaxy Candidates Involved in Interactions

open access: yesResearch Notes of the AAS, 2021
Abstract Galaxy mergers are a mechanism for rapid quenching of star formation. We are studying E+A galaxies (a type of post-starburst galaxy) and how they are impacted by merging. Examining E+A galaxies with companions offers insight into the evolution of E+As and the quenching process.
