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…
Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA
Shenli Tang, John D. Silverman, Zhaoxuan Liu +12
We present a study of the molecular gas in five closely-spaced ( kpc) dual quasars () at redshifts with the…
Discovery of merging twin quasars at z = 6.05
Yoshiki Matsuoka, Takuma Izumi, Masafusa Onoue +14
We report the discovery of two quasars at a redshift of = 6.05, in the process of merging. They were serendipitously discovered from the deep multi-band imaging data collected…
Merging gas-rich galaxies that harbor low-luminosity twin quasars at z = 6.05: a promising progenitor of the most luminous quasars
Takuma Izumi, Yoshiki Matsuoka, Masafusa Onoue +15
We present ALMA [CII] 158 m line and underlying far-infrared (FIR) continuum emission observations ( resolution) toward a quasar-quasar pair system recentl…
Cosmic Himalayas: The Highest Quasar Density Peak Identified in a 10,000 deg Sky with Spatial Discrepancies between Galaxies, Quasars, and IGM HI
Yongming Liang, Masami Ouchi, Dongsheng Sun +27
We report the identification of a quasar overdensity in the BOSSJ0210 field, dubbed Cosmic Himalayas, consisting of 11 quasars at , the densest overdensity of quasars…
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…
Steep-spectrum AGN in eROSITA Final Equatorial-Depth Survey (eFEDS): Their host galaxies and multi-wavelength properties
K. Iwasawa, T. Liu, Th. Boller +12
We selected sources with a steep soft-X-ray-band spectrum with a photon index larger than 2.5 -- measured by eROSITA on board the Spectrum-Roentgen-Gamma (SRG) -- from the eFEDS AG…
Two rest-frame wavelength measurements of galaxy sizes at : the evolutionary effects of emerging bulges and quenched newcomers
Angelo George, Ivana Damjanov, Marcin Sawicki +6
We analyze the size evolution of star-forming galaxies (SFGs) and quiescent galaxies (QGs) with mass at from the COSMOS field using…
