The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at z = 1.14
The Astrophysical JournalGalaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei (AGN), and stimulating star formation.

High-velocity outflows persist up to 1 Gyr after a starburst in recently quenched galaxies at z > 1 [PDF]
High-velocity outflows are ubiquitous in star-forming galaxies at cosmic noon, but are not as common in passive galaxies at the same epoch. Using optical spectra of galaxies selected from the UKIDSS Ultra Deep Survey at z > 1, we perform a stacking ...

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

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 ...

The first detection of dense gas in a massive main-sequence galaxy at cosmic noon
Astronomy & AstrophysicsDense 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 Delay Time Distribution of Tidal Disruption Events
The Astrophysical JournalTidal 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 ...

Massive dusty multiphase outflow in local merger shows no sign of slowing on kiloparsec scales
Astronomy & AstrophysicsWe use ALMA CO(1-0) observations and VLT/MUSE rest-frame optical data of the ultraluminous infrared galaxy (ULIRG) IRAS20100-4156 at z = 0.1297 to characterize its powerful outflow in multiple phases using tracers of cold molecular, ionized, and neutral ...
