The Rise of Faint, Red AGN at : A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields
Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro +54
We present a sample of 341 "little red dots" (LRDs) spanning the redshift range using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. Unlike past use of…
Exploring Low-Mass Black Holes through Tidal Disruption Events in the Early Universe: Perspectives in the Era of JWST, RST, and LSST Surveys
Kohei Inayoshi, Kazumi Kashiyama, Wenxiu Li +3
The James Webb Space Telescope (JWST) has recently uncovered the presence of low-luminosity active galactic nuclei (AGNs) at . Spectroscopic observations have provided esti…
Reconstruction of Cosmic Black Hole Growth and Mass Distribution from Quasar Luminosity Functions at : Implications for Faint and Low-mass Populations in JWST
Wenxiu Li, Kohei Inayoshi, Masafusa Onoue +6
The evolution of the quasar luminosity function (QLF) is fundamental to understanding the cosmic evolution of black holes (BHs) through their accretion phases. In the era of the Ja…
Hidden Little Monsters: Spectroscopic Identification of Low-Mass, Broad-Line AGN at with CEERS
Dale D. Kocevski, Masafusa Onoue, Kohei Inayoshi +34
We report on the discovery of two low-luminosity, broad-line AGN at identified using JWST NIRSpec spectroscopy from the CEERS Survey. We detect broad H emission from both…
The Assembly of Black Hole Mass and Luminosity Functions of High-redshift Quasars via Multiple Accretion Episodes
Wenxiu Li, Kohei Inayoshi, Masafusa Onoue +1
The early evolution of the quasar luminosity function (QLF) and black hole mass function (BHMF) encodes key information on the physics determining the radiative and accretion proce…
A Lower Bound of Star Formation Activity in Ultra-high Redshift Galaxies Detected with JWST: Implications for Stellar Populations and Radiation Sources
Kohei Inayoshi, Yuichi Harikane, Akio K. Inoue +2
Early results of JWST observations have delivered bright galaxy candidates in greater numbers than expected, enabling construction of the rest-frame UV luminosity fun…
A Candidate of a Least-Massive Black Hole at the First 1.1 Billion Years of the Universe
Masafusa Onoue, Kohei Inayoshi, Xuheng Ding +6
We report a candidate of a low-luminosity active galactic nucleus (AGN) at z=5 that was selected from the first near-infrared images of the JWST CEERS project. This source, named C…
Radiative feedback on supermassive star formation: the massive end of the Population III initial mass function
Daisuke Toyouchi, Kohei Inayoshi, Wenxiu Li +2
Supermassive stars (SMSs) with masses of -- are invoked as possible seeds of high-redshift supermassive black holes, but it remains under de…
Supercritical growth pathway to overmassive black holes at cosmic dawn: coevolution with massive quasar hosts
Haojie Hu, Kohei Inayoshi, Zoltán Haiman +3
Observations of the most luminous quasars at high redshifts () have revealed that the largest supermassive black holes (SMBHs) at those epochs tend to be substantially overm…
