SHELLQs. Black Hole Mass and Eddington Ratio Distributions of Intermediate-Luminosity Quasars at 6<z<7
Masafusa Onoue, John D. Silverman, Yoshiki Matsuoka +31
We present near-infrared spectroscopy of 21 quasars at 6.07 < z < 6.90 obtained with JWST/NIRSpec and Subaru/MOIRCS. These targets have absolute ultraviolet magnitudes of -25 < M_1…
Statistical inference of fast radio burst environments using galaxy number density
Vignesh V. V. Rao, Tetsuya Hashimoto, Tomotsugu Goto +9
Fast radio bursts (FRBs) are bright, millisecond-duration radio transients of unknown origin. They are categorized as repeaters and non-repeaters, possibly indicating distinct prog…
Tracing Obscured AGN Contribution and Number Fraction Across 0 < z < 6 with JWST
Angel Rodriguez Barbosa, Tomotsugu Goto, Daryl Joe D. Santos +8
Active galactic nuclei (AGN) are key drivers of galaxy evolution, yet many remain undetected in ultraviolet and optical surveys due to heavy dust obscuration. In these systems, abs…
Mid-IR luminosity functions: inferred dusty cosmic star-formation and black hole accretion histories from the JWST SMILES
Chih-Teng Ling, Tomotsugu Goto, Seong Jin Kim +5
Mid-infrared (mid-IR) observations are crucial for understanding galaxy evolution, tracing star formation, and active galactic nuclei (AGN) activity via dust emission. This work pr…
JWST MIRI color classification of mid-infrared selected galaxies: MIRI color classification toward cosmic noon
Ece Kilerci, Tomotsugu Goto, Matthew A. Malkan +7
We investigated the James Webb Space Telescope photometric color classification of mid-infrared (MIR) selected galaxies at high redshifts, toward cosmic noon. The aim of the presen…
Photometrically Selected Protocluster Candidates at z~9-10 in the JWST COSMOS-Web field
Cossas K. -W. Wu, Chih-Teng Ling, Tomotsugu Goto +8
High-redshift protoclusters are crucial for understanding the formation of galaxy clusters and the evolution of galaxies in dense environments. The James Webb Space Telescope (JWST…
