The Rise of Faint, Red AGN at $z>4$: A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro, Anthony J. Taylor, Antonello CalabrĂ² | Summary: We present a sample of 341 "little red dots" (LRDs) spanning the redshift range $zsim2-11$ using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. These sources are likely heavily-reddened AGN […]

Relation between the keV-MeV and TeV emission of GRB 221009A and its implications

Kavli Affiliate: Zhuo Li | First 5 Authors: Yan-Qiu Zhang, Hao-Xiang Lin, Shao-Lin Xiong, Zhuo Li, Ming-Yu Ge | Summary: Gamma-ray bursts (GRBs) are believed to launch relativistic jets, which generate prompt emission by their internal processes and drive external shocks into surrounding medium, accounting for the long-lasting afterglow emission. However, how the jet powers […]

Radio Scrutiny of the X-ray-Weak Tail of Low-Mass Active Galactic Nuclei: A Novel Signature of High-Eddington Accretion?

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jeremiah D. Paul, Richard M. Plotkin, W. N. Brandt, Christopher H. Ellis, Elena Gallo | Summary: The supermassive black holes ($M_{rm BH} sim 10^{6}$$-$$10^{10}~M_odot$) that power luminous active galactic nuclei (AGNs), i.e., quasars, generally show a correlation between thermal disk emission in the ultraviolet (UV) and […]
