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 ...

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 ...

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.

Sparks: The Magellan/FIRE Survey from Starburst to Post-starburst

The Astrophysical Journal
Rapid transitions from starburst to quiescence constitute a key evolutionary pathway in galaxy formation. Post-starburst galaxies trace this brief phase, exhibiting optical spectra dominated by intermediate-age stellar populations with strong Balmer ...

Equivalent width Measurements in Optical Spectra of Galaxies in Local Clusters: Hints On the Star Formation History in Clusters

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.

Cool Gas in the Circumgalactic Medium of Massive Post Starburst Galaxies

The Open Journal of Astrophysics
Observing 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.

Cold Gas in a Post-starburst Pair in the z ∼ 1.4 HeavyMetal Survey: Major Mergers as a Pathway to Retain Gas in Quenched Galaxies

The Astrophysical Journal
Recent 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 ...

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.
