The Astrophysical Journal LettersRestricted by event horizon suppression, tidal disruption events (TDEs) provide a unique window into otherwise hidden supermassive black holes (SMBHs) at the lower end of the mass spectrum, allowing the connection between star formation and SMBH mass to ...

The Open Journal of AstrophysicsMechanisms for quenching star formation in galaxies remain hotly debated, with galaxy mergers an oft-proposed pathway. In Ellison et al. (2022) we tested this scenario by quantifying the fraction of recently and rapidly quenched post-starbursts (PSBs) in

PAC. V. The Roles of Mass and Environment in the Quenching of Galaxies
The Astrophysical JournalThe roles that mass and environment play in galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs method, we analyze the excess surface distribution ${\bar{n}}_{2}{w}_{{\rm{p}}}({r}_{{\rm{p}}})$ of photometric ...

The connection between dusty star-forming galaxies and the first massive quenched galaxies
Astronomy & AstrophysicsHigh-redshift (z ≳ 2) massive quiescent galaxies (MQs) provide an opportunity to probe the key physical processes driving the fuelling and quenching of star formation in the early Universe.

The Role of Gas Stripping in the Quenching of Satellite Galaxies Using SHARK v2.0
The Astrophysical JournalObservational studies have made substantial progress in characterizing quenching as a function of galaxy stellar mass and environment, but they are often limited in their ability to constrain quenching timescales and to determine the dominant ...

Quenching of galaxies at cosmic noon
Astronomy & AstrophysicsContext. We identified and analysed massive quiescent galaxies (MQGs) at z ≈ 3.1 within the 2 deg2 COSMOS field and explored the effect of the galaxy environment on quenching processes. By examining the variation in the quenched fraction and physical properties of these galaxies in different environmental contexts, including local densities ...

Merger Shocks Enhance Quenching in Local Galaxy Clusters
The Astrophysical JournalAbstract We report evidence for enhanced quenching in low-redshift galaxy clusters hosting radio relics. This effect is strongest for low-mass galaxies and is consistent with a rapid quenching of star formation. These results imply that merger shocks in the intracluster medium play a role in driving environmental quenching, which we ...
