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 ...

A Rare Eddington-limited, Heavily Obscured Low-mass Active Galactic Nucleus Likely Triggered by a Galaxy Merger

The Astrophysical Journal
We report a detailed analysis of GAMA 376183, a powerful, heavily obscured active galactic nucleus (AGN) hosted by a low-mass galaxy ( M _⋆  ≈ 10 ^10 M _⊙ ) likely experiencing a galaxy merger.

Green Peas in the Southern Sky: Broadband Color Selection and Spectroscopic Follow-up

The Astrophysical Journal
We present a systematic search for 1696 green pea (GP) galaxy candidates in the southern hemisphere selected from the Dark Energy Survey Data Release 2 and provide preliminary results from spectroscopic follow-up observations of 26 targets chosen among ...
