Anisotropic quenching beyond and its implications for preprocessing around high-redshift galaxy clusters

Makoto Ando, Kazuhiro Shimasaku, Kei Ito +2

Recent studies have shown that, within galaxy clusters, quenched satellite galaxies tend to be distributed preferentially along the major axis of the central galaxy, dubbed anisotr…

Merger-driven buildup of the - relation bridging high- overmassive black holes with the local relation

Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +3

The origin of the mass scaling relation between supermassive black holes (SMBHs, ) and galaxies () remains a key open question. Rather than invoking AGN feedback,…

JWST MIRI/MRS observations of hot molecular gas in an AGN host galaxy at Cosmic Noon

D. Kakkad, V. Mainieri, Takumi S. Tanaka +27

Active Galactic Nuclei (AGN) are believed to play a central role in quenching star formation by removing or destroying molecular gas from host galaxies via radiation-pressure drive…

Clumps as multiscale structures in cosmic noon galaxies

Boris S Kalita, Tomoko L Suzuki, Daichi Kashino +31

Star-forming clumps have been found to significantly influence the star formation of gas-rich galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS)…

Tip of the iceberg: overmassive black holes at 4<z<7 found by JWST are not inconsistent with the local - relation

Junyao Li, John D. Silverman, Yue Shen +8

JWST is revealing a new remarkable population of high-redshift (), low-luminosity Active Galactic Nuclei (AGNs) in deep surveys and detecting the host galaxy stellar lig…

X-ray stacking reveals average SMBH accretion properties of star-forming galaxies and their cosmic evolution over 4 <~ z <~ 7

Suin Matsui, Kazuhiro Shimasaku, Kei Ito +2

With an X-ray stacking analysis of ~ 12, 000 Lyman-break galaxies (LBGs) using the Chandra Legacy Survey image, we investigate average supermassive black hole (SMBH) accretion prop…
