Post-starburst Galaxies in the Centers of Intermediate-redshift Clusters
The Astrophysical Journal, 2022 Abstract We present results from MUSE spatially resolved spectroscopy of 21 post-starburst galaxies in the centers of eight clusters from z ∼ 0.3 to z ∼ 0.4. We measure spatially resolved star formation histories (SFHs), the time since quenching (t Q ), and the fraction of stellar

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.

Evidence for multiple types of post-starburst galaxies [PDF]
Astronomy & AstrophysicsThe quenching mechanisms of galaxies are not yet fully understood, but post-starburst galaxies provide one explanation for the rapid transition between star-forming and quiescent galaxies. At low redshift, it is generally thought that the starburst initiating the post-starburst phase is merger-driven, however, not all post-starburst galaxies show ...

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 −.

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 (

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.

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).

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-

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 ...
