A Census of Photometrically Selected Little Red Dots at 4 < z < 9 in JWST Blank Fields
arxiv(2024)
摘要
Observations with the James Webb Space Telescope (JWST) have uncovered
numerous faint active galactic nuclei (AGN) at z∼5 and beyond. These
objects are key to our understanding of the formation of supermassive black
holes (SMBHs), their co-evolution with host galaxies, as well as the role of
AGN in cosmic reionization. Using photometric colors and size measurements, we
perform a search for compact red objects in an array of blank deep JWST/NIRCam
fields totaling ∼340 arcmin^2. Our careful selection yields 260
reddened AGN candidates at 4更多
