A Simple Spectroscopic Technique to Identify Rejuvenating Galaxies
The Astrophysical Journal, 2023 Rejuvenating galaxies are unusual galaxies that fully quench and then subsequently experience a “rejuvenation” event to become star-forming once more. Rejuvenation rates vary substantially in models of galaxy formation: 10%–70% of massive galaxies are ...

Open Astronomy, 2011 Equivalent widths of spectral lines in the optical spectra of galaxies are commonly used to characterize their stellar populations and to get some insight on their evolution.

, 2010 We have used the Low Resolution Imaging Spectrograph (LRIS) on the W.M. Keck I telescope to obtain spatially resolved spectroscopy of a small sample of six post-starburst and three dusty-starburst galaxies in the rich cluster CL0016+16 at z=0.55.

Group-cluster merging and the formation of starburst galaxies [PDF]
, 1998 A significant fraction of clusters of galaxies are observed to have substructure, which implies that merging between clusters and subclusters is a rather common physical process of cluster formation. It still remains unclear how cluster merging affects

Post‐starburst galaxies and the transformation of blue into red galaxies [PDF]
Astronomische Nachrichten, 2009 AbstractWe present deep single‐dish radio observations of a sample of nearby post‐starburst galaxies (0.05 < z < 0.1). About 50% of these post‐starburst galaxies are detected at 21 cm, with HI masses of ∼109 M⊙, up to ∼1010 M⊙. These post‐starburst galaxies are as gas‐rich as spiral galaxies with comparable luminosities. There appears to exist no

Excess Of Post-Starburst Galaxies In Distant Galaxy Clusters
, 2017 I present a study on the impact of environment on galaxy evolution in distant galaxy clusters between redshifts 0.5 and 1.0. We find candidate galaxy clusters by applying a friends-of-friends algorithm to the deep photometric data of the UKIDSS Ultra-Deep Survey. Through studying the stellar mass functions, we reveal a strong excess of low-mass rapidly-

Halpha-Derived Star-Formation Rates For Three z ~ 0.75 EDisCS Galaxy Clusters [PDF]
, 2005 We present Halpha-derived star-formation rates (SFRs) for three z ~ 0.75 galaxy clusters. Our 1 sigma flux limit corresponds to a star-formation rate of 0.10-0.24 solar mass per year, and our minimum reliable Halpha + [N II] rest-frame equivalent width ...

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics
Annalen der Physik, Volume 536, Issue 2, February 2024.Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

Cool Gas in the Circumgalactic Medium of Massive Post Starburst Galaxies
The Open Journal of AstrophysicsObserving the interplay between galaxies and their gaseous surroundings is crucial for understanding how galaxies form and evolve, including the roles of long-lived cool gas reservoirs, starburst and AGN driven outflows.
