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.

The cold gas content of post-starburst galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 Post-starburst galaxies, or E+A galaxies, are characterized by optical spectra showing strong Balmer absorption lines, indicating a young stellar population, and little or no emission lines, implying no active star formation. These galaxies are interpreted as a transitional population between star-forming, disc-dominated galaxies and spheroidal ...

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.

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 ...

Current Star Formation in Post-Starburst Galaxies? [PDF]
The Astrophysical Journal, 2001 Radio continuum observations are a probe of star formation in galaxies, and are unaffected by dust extinction. Observations of the distant rich cluster Cl 0939+4713 have detected radio galaxies classified as post-starburst (``k+a'') on the basis of their optical spectra, and presumably this situation arises from heavily dust-obscured star formation ...

The Astrophysical JournalRecent observations at low redshift have revealed that some post-starburst galaxies retain significant molecular gas reservoirs despite low ongoing star formation rates, challenging most theoretical predictions that rely on heating or expelling gas ...

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

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]
, 2005 Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...
