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…
Black hole mass of a quiescent galaxy hosting a Type 1 AGN at z=2.09: Implications for black hole - galaxy co-evolution and AGN quenching at high redshift
Kei Ito, Takumi S. Tanaka, Kazuhiro Shimasaku +6
We report a characterization of an X-ray-detected quiescent galaxy at , named COS-XQG1, using JWST/NIRCam and NIRSpec data. This galaxy is detected in Chandra imaging, sugg…
Cluster candidates with massive quiescent galaxies at
Tomokazu Kiyota, Makoto Ando, Masayuki Tanaka +7
Galaxy clusters are crucial to understanding role of the environment in galaxy evolution. However, due to their rarity, only a limited number of clusters have been identified at $z…
