Hidden in Pixels. I. Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales
Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56
``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…
Weakness of X-rays and Variability in High-redshift AGNs with Super-Eddington Accretion
Kohei Inayoshi, Shigeo S. Kimura, Hirofumi Noda
The James Webb Space Telescope (JWST) observations enable the exploration of active galactic nuclei (AGNs) with broad-line emission in the early universe. Despite their clear radia…
A Search for H and H[O III] Dual-Line Emitting Galaxies in the JWST CEERS Field: Implications for the AGN Abundance
Jingsong Guo, Masafusa Onoue, Kohei Inayoshi +4
The James Webb Space Telescope (JWST) has enabled us to uncover faint galaxies and active galactic nuclei (AGNs) in the early universe. Taking advantage of the unique filter combin…
Gravitational Wave Astronomy With TianQin
En-Kun Li, Shuai Liu, Alejandro Torres-Orjuela +50
The opening of the gravitational wave window has significantly enhanced our capacity to explore the universe's most extreme and dynamic sector. In the mHz frequency range, a divers…
Gravitational Wave Forecasts Constrained by JWST AGN Observations for Early Massive Black Hole Mergers
Hanpu Liu, Kohei Inayoshi
Massive black holes (BHs) grow by gas accretion and mergers, observable through electromagnetic (EM) and gravitational wave (GW) emission. The James Webb Space Telescope (JWST) has…
Extremely Dense Gas around Little Red Dots and High-redshift Active Galactic Nuclei: A Non-stellar Origin of the Balmer Break and Absorption Features
Kohei Inayoshi, Roberto Maiolino
The James Webb Space Telescope (JWST) has uncovered low-luminosity active galactic nuclei (AGNs) at high redshifts of , powered by accreting black holes (BHs) with ma…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
Broad-Line AGN at 3.5<z<6: The Black Hole Mass Function and a Connection with Little Red Dots
Anthony J. Taylor, Steven L. Finkelstein, Dale D. Kocevski +48
We present a sample of 50 H-alpha detected broad-line active galactic nuclei (BLAGN) at redshifts 3.5<z<6.8 using data from the CEERS and RUBIES surveys. We select these sources di…
Towards a universal analytical model for Population III star formation: interplay between feedback and fragmentation
Boyuan Liu, James Gurian, Kohei Inayoshi +4
JWST has brought us new insights into Cosmic Dawn with tentative detection of the unique signatures of metal-free Population III (Pop III) stars, such as strong HeII emission, extr…
Little Red Dots: Rapidly Growing Black Holes Reddened by Extended Dusty Flows
Zhengrong Li, Kohei Inayoshi, Kejian Chen +2
The James Webb Space Telescope (JWST) observations have revolutionized extragalactic research, particularly with the discovery of little red dots (LRD), which we propose are dust-r…
Radiation hydrodynamical simulations of super-Eddington mass transfer and black hole growth in close binaries
Daisuke Toyouchi, Kenta Hotokezaka, Kohei Inayoshi +1
Radiation-driven outflows play a crucial role in extracting mass and angular momentum from binary systems undergoing rapid mass transfer at super-Eddington rates. To study the mass…
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…
Birth of Rapidly Spinning, Overmassive Black Holes in the Early Universe
Kohei Inayoshi, Kohei Ichikawa
The James Webb Space Telescope (JWST) has unveiled numerous massive black holes (BHs) in faint, broad-line active galactic nuclei (AGNs). The discovery highlights the presence of d…
