Optical polarimetry studies of Seyfert galaxies [PDF]

, 1999
Optical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications.

Sparks. II. Panchromatic Spectral Energy Distribution Modeling and Galaxy Physical Properties across the Starburst to Post-starburst Sequence

The Astrophysical Journal
The Sparks survey provides rest-frame near-infrared spectroscopy for 93 local massive galaxies spanning the rapid transition from starburst to post-starburst, including Balmer-strong galaxies as well as systems with active galactic nuclei (AGNs ...

The origin and fate of post-starburst galaxies : morphological and structural image analysis of local galaxies with recent episodes of enhanced star formation [PDF]

, 2016
Post-starburst galaxies are a rare class of objects with unusual spectroscopic characteristics. Previous studies have shown that the presence of strong Balmer absorption lines in the spectra of these galaxies are consistent with a recent bust of star ...

DESI Massive Poststarburst Galaxies at z ∼ 1.2 Have Compact Structures and Dense Cores

The Astrophysical Journal
Poststarburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of galaxy evolution.

SQuIGG E: Observational Evidence of Low Ongoing Star Formation Rates in Gas-rich Post-starburst Galaxies

The Astrophysical Journal
Atacama Large Millimeter/submillimeter Array observations have shown that candidate “post-starburst” galaxies (PSBs) at z  ∼ 0.6 can retain significant molecular gas reservoirs.

The Delay Time Distribution of Quasiperiodic Eruptions

The Astrophysical Journal Letters
Quasiperiodic eruptions (QPEs) are quasiperiodic X-ray bursts observed in the nucleus of a galaxy. Multiple pieces of observational evidence link QPEs to tidal disruption events (TDEs), which occur when stars are disrupted after approaching a ...

The Evolution of Post-starburst Galaxies from z ∼1 to the Present

, 2016
Post-starburst galaxies are in the transitional stage between blue, star-forming galaxies and red, quiescent galaxies and therefore hold important clues for our understanding of galaxy evolution.

Decoding the Single-peaked H i Spectra of Low Redshift Poststarburst Galaxies

The Astrophysical Journal
Recent observations with the Five-hundred-meter Aperture Spherical Telescope have revealed abundant reservoirs of neutral hydrogen (H I ) in low-redshift poststarburst galaxies (PSBs), raising the question of why star formation ceases rapidly in these ...
