Low redshift post-starburst galaxies host abundant HI reservoirs

The Open Journal of Astrophysics
Studying the gas content of post-starburst (PSB) galaxies can provide valuable clues regarding the process of fast quenching. Although previous works have studied the molecular gas content of PSBs, only a handful of HI measurements exist.

The infrared luminosity of retired and post-starburst galaxies: A cautionary tale for star formation rate measurements

The Open Journal of Astrophysics
In galaxies with significant ongoing star formation there is an impressively tight correlation between total infrared luminosity (L${\mathstrut}_{TIR}$) and H$\alpha$ luminosity (L${\mathstrut}_{H\alpha}$), when H$\alpha$ is properly corrected for ...

266 E+A Galaxies Selected from the Sloan Digital Sky Survey Data Release 2: The Origin of E+A Galaxies

, 2005
E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any [OII] nor H$\alpha$ emission lines. The existence of strong Balmer absorption lines indicates that E+A galaxies have experienced starburst within recent one ...

Dissecting the γ-Ray Emissions of the Nearby Galaxies NGC 1068 and NGC 253

The Astrophysical Journal
Intrigued by recent high-energy study results for nearby galaxies with γ -ray emission and in particular NGC 1068 that has been detected as a neutrino-emitting source by the IceCube Neutrino Observatory, we conduct a detailed analysis of the γ -ray data ...

Can Supernovae Quench Star Formation in High-z Galaxies?

The Astrophysical Journal
JWST is providing a unique opportunity to directly study the feedback processes regulating star formation (SF) in early galaxies. The two z > 5 quiescent systems (JADES-GS-z7-01-QU and MACS0417-z5BBG) detected so far show a recent starburst after which ...

On the Origins of Starburst and Post-Starburst Galaxies in Nearby Clusters

, 1998
HST WFPC2 images in B (F450W) and I (F814W) have been obtained for three starburst (SB) and two post-starburst (PSB) galaxies in the Coma cluster, and for three such galaxies in the cluster DC2048-52.

Resolving the Nuclear Environments of Tidal Disruption Event Host Galaxies within 45 pc

The Astrophysical Journal
Using Hubble Space Telescope/Space Telescope Imaging Spectrograph observations, we present the highest-spatial-resolution spectroscopic study to date of four tidal disruption event (TDE) host galaxies, with the best observed being the post-starburst host

A Multiwavelength Evaluation of AGN in the Post-starburst Phase

The Astrophysical Journal
The quenching of star formation is a crucial phase in galaxy evolution. Although feedback from active galactic nuclei (AGN) has been proposed as a key driver of this transition, the lack of strong AGN in nearby quenching galaxies raises questions about ...
