Predicting Ly Emission from Distant Galaxies with Neural Network Architecture

Takehiro Yoshioka, Nobunari Kashikawa, Yoshihiro Takeda +7

The Ly emission line is a characteristic feature found in high- galaxies, serving as a probe of cosmic reionization. While previous works present various correlations between…

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…

Mining for Protoclusters at from Photometric Datasets with Deep Learning

Yoshihiro Takeda, Nobunari Kashikawa, Kei Ito +9

Protoclusters are high- overdense regions that will evolve into clusters of galaxies by , making them ideal for studying galaxy evolution expected to be accelerated by envi…

JWST/NIRSpec spectroscopy of intermediate-mass quiescent galaxies at

Riku A. Sato, Akio K. Inoue, Yuichi Harikane +9

We present the analysis of three intermediate-mass quiescent galaxies (QGs) with stellar masses of at redshifts using NIRSpec low-resolutio…

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…

Galaxy properties from the outskirts to the core of a protocluster at z=3.699

Jun Toshikawa, Stijn Wuyts, Nobunari Kashikawa +6

We present follow-up spectroscopy on a protocluster candidate selected from the wide-field imaging of the Hyper SuprimeCam Subaru Strategic Programme. The target protocluster candi…

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…
