Rise and fall of post-starburst galaxies in Magneticum Pathfinder [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Post-starburst (PSB) galaxies belong to a short-lived transition population between star-forming (SF) and quiescent galaxies. Deciphering their heavily discussed evolutionary pathways is paramount to understanding galaxy evolution.

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

Science 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 −.

Fading AGN in Post-Starburst Galaxies

, 2023
The role of AGN in quenching galaxies and driving the evolution from star-forming to quiescent remains a key question in galaxy evolution. We present evidence from the Mapping Nearby Galaxies at APO (MaNGA) survey for fading AGN activity in 6/93 post ...

AGN/Starburst Connection

Acta Polytechnica CTU Proceedings, 2014
Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN).

After the Fall: The Dust and Gas in E+A Post-starburst Galaxies [PDF]

The Astrophysical Journal, 2018
Abstract The traditional picture of post-starburst galaxies as dust- and gas-poor merger remnants, rapidly transitioning to quiescence, has been recently challenged. Unexpected detections of a significant interstellar medium (ISM) in many post-starburst galaxies raise important questions.

Star formation and molecular gas properties of post-starburst galaxies

, 2023
Post-starburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals. Their optical spectrum is dominated by A-type stars, suggesting a starburst that was quenched recently. While optical observations

On Post-starburst Galaxies Dominating Tidal Disruption Events [PDF]

The Astrophysical Journal Letters, 2020
Abstract A starburst induced by a galaxy merger may create a relatively thin central stellar disk at radius ≤100 pc. We calculate the rate of tidal disruption events (TDEs) by the inspiraling secondary supermassive black hole (SMBH) through the disk. With a small enough stellar velocity dispersion (

Cosmic Sands: The Origin of Dusty, Star-forming Galaxies in the Epoch of Reionization

The Astrophysical Journal, 2023
We present the Cosmic Sands suite of cosmological zoom-in simulations based on the simba galaxy formation model in order to study the buildup of the first massive and dusty galaxies in the early universe.

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 ...
