A Rare Eddington-Limited, Heavily Obscured Low-Mass Active Galactic Nucleus Likely Triggered by a Galaxy Merger
Shouyi Wang, Fan Zou, Chang-Hao Chen +7
We report a detailed analysis of GAMA 376183, a powerful, heavily obscured active galactic nucleus (AGN) hosted by a low-mass galaxy () likely ex…
The Physical Nature of the Off-centered Extended Emission Associated with the Little Red Dots
Chang-Hao Chen, Luis C. Ho, Ruancun Li +1
A significant fraction of little red dots (LRDs) exhibit nearby extended emission of unknown origin. If physically associated with the LRD, this component may trace stellar emissio…
The Dichotomy in the Nuclear and Host Galaxy Properties of High-redshift Quasars
Ruancun Li, Luis C. Ho, Chang-Hao Chen
The early growth of high-redshift quasars and their host galaxies raises critical questions about their cosmic evolution. We exploit the angular resolution and sensitivity of NIRCa…
The Host Galaxy (If Any) of the Little Red Dots
Chang-Hao Chen, Luis C. Ho, Ruancun Li +1
We investigate the host galaxy properties of eight little red dots (LRDs) selected from the JWST UNCOVER survey, applying a new technique ({\tt\string GalfitS}) to simultaneously f…
