Starbursts and Galaxy Evolution

, 2004
Starbursts are extreme concentrations of star-forming activity with mass conversion surface densities reaching over 1000 times higher than normal for disk galaxies. They are responsible for a large fraction of all cosmic star formation. They have shaped the cosmic landscape not just in individual galaxies but though the effects of "superwinds" that ...

Death by Impact: Evidence for Merger-driven Quenching in a Collisional Ring Galaxy at Cosmic Noon

The Astrophysical Journal
The role of interactions and mergers in the rapid quenching of massive galaxies in the early Universe remains uncertain, largely due to the difficulty of directly linking mergers to quenching.

The first detection of dense gas in a massive main-sequence galaxy at cosmic noon

Astronomy & Astrophysics
Dense gas is the direct fuel for star formation, but measuring it has long been difficult at z ≥ 2, especially in unlensed star-forming main-sequence galaxies.

The ultraviolet signature of massive stars in starburst galaxies [PDF]

, 1993
Studies in different spectral regimes of starburst galaxies clearly indicate the presence of hot, massive stars. However, only the UV spectral region can be used to directly identify the spectroscopic signature of these stars.

The Delay Time Distribution of Tidal Disruption Events

The Astrophysical Journal
Tidal disruption events (TDEs) can be observed when stars get too close to supermassive black holes and are torn apart and accreted. The delay time distribution of TDEs, or rate of TDEs as a function of time since a burst of star formation, can be used ...

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 ...

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 ...
