A Census of Quiescent Galaxies across 0.5 < z < 8 with JWST/MIRI: Mass-dependent Number Density Evolution of Quiescent Galaxies in the Early Universe

The Astrophysical Journal Letters
Recent JWST observations have revealed a large population of quiescent galaxies (QGs) at high redshift ( z  ∼ 4–8), challenging current models of early galaxy formation and quenching. Accurate number density estimates are crucial but remain uncertain. We

The FENIKS Survey: Spectroscopic Confirmation of Massive Quiescent Galaxies at z ∼ 3–5

The Astrophysical Journal
The measured ages of massive, quiescent galaxies at z ∼ 3–4 imply that massive galaxies quench as early as z ∼ 6. While the number of spectroscopic confirmations of quiescent galaxies at z < 3 has increased over the years, there are only a handful at z >

Post-Starburst Galaxies in Clusters from the GASP Survey.

, 2018
Post-starburst galaxies, also known as k+a galaxies, show no sign of emission lines and prominent Balmer absorption lines in their spectra. They are in a transitional phase between the star forming and the passive galaxies. I present here the study of a

The molecular gas content throughout the low-z merger sequence

The Open Journal of Astrophysics
Exploiting IRAM 30 m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50\%, a mildly increased CO excitation, and standard molecular-to-atomic gas ratios, compared to non-interacting ...

The Fate of the Interstellar Medium in Early-type Galaxies. III. The Mechanism of Interstellar Medium Removal and the Quenching of Star Formation

The Astrophysical Journal
Understanding how galaxies quench their star formation is crucial for studies of galaxy evolution. Quenching is related to a decrease of cold gas. In the first paper we showed that the dust removal timescale in early-type galaxies (ETGs) is about 2.5 Gyr.

Starburst galaxies

, 2006
Star formation and the Starburst phenomenon are presented with respect to a number of nearby star-forming galaxies where our understanding of the process can be calibrated.

High-redshift Post-starburst Galaxies from the Sloan Digital Sky Survey

, 2015
Post-starburst galaxies are a rare class of galaxy that show the spectral signature of recent, but not ongoing, star-formation activity, and are thought to have their star formation suddenly quenched within the one billion years preceding the ...
