Discovery of Large Molecular Gas Reservoirs in Post-Starburst Galaxies [PDF]

, 2015
Post-starburst (or E+A ) galaxies are characterized by low Hα emission and strong Balmer absorption, suggesting a recent starburst, but little current star formation.

The Evolutionary Sequence of Post-Starburst Galaxies [PDF]

, 2017
There are multiple ways in which to select post-starburst galaxies in the literature. In this work, we present a study into how two well-used selection techniques have consequences on observable post-starburst galaxy parameters, such as colour ...

The Nature of Starburst Galaxies

The Astrophysical Journal, 1996
Utilizing a large sample of infrared-selected starburst galaxies having optical images and long-slit spectra, we explore the interrelationships between the properties of starbursts and relate these properties to those of the "host" galaxy. We find that the half-light radius of the Hα-emitting region (re, Hα) enters into several correlations that ...

The evolution of stars and gas in starburst galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2003
In systems undergoing starbursts the evolution of the young stellar population is expected to drive changes in the emission line properties. This evolution is usually studied theoretically, with a combination of evolutionary synthesis models for the spectral energy distribution of starbursts and photoionization calculations.

Unveiling the evolutionary history of local post-starburst galaxies through careful Bayesian modelling of their spectra

When we gaze upon the night sky into the stars in the Milky Way, it seems that the cosmos is constant, at least in the timescale of a lifetime. However, as our telescopes continued to improve, we have discovered that galaxies are instead dynamic systems,

Cosmic axion background propagation in galaxies

Physics Letters B, 2016
Many extensions of the Standard Model include axions or axion-like particles (ALPs). Here we study ALP to photon conversion in the magnetic field of the Milky Way and starburst galaxies. By modelling the effects of the coherent and random magnetic fields,

The diverse evolutionary pathways of post-starburst galaxies [PDF]

, 2019
About 35 years ago a class of galaxies with unusually strong Balmer absorption lines and weak emission lines was discovered in distant galaxy clusters.

First Detection of CO Isotopologues in a High-redshift Main-sequence Galaxy: Evidence of a Top-heavy Stellar Initial Mass Function

The Astrophysical Journal
Recent observations and theories have presented a strong challenge to the universality of the stellar initial mass function (IMF) in extreme environments. A notable example has been found for starburst conditions, where evidence favors a top-heavy IMF, i.

SQuIGG E: Buried Star Formation Cannot Explain the Rapidly Fading CO(2–1) Luminosity in Massive, z ∼ 0.7 Post-starburst Galaxies

The Astronomical Journal
Observational and theoretical studies have long held that rapid gas consumption in starbursts is responsible for the formation of the most massive quiescent galaxies at high redshift.
