Diverse Protoclusters at Disclosed by Systematic Spectroscopy
Jun Toshikawa, Kentaro Koretomo, Nobunari Kashikawa +6
We present the results from follow-up spectroscopy of three protocluster candidates at , selected as overdense regions of -dropout galaxies in the wide-field imaging of…
Diverse Metallicities in Protoclusters at detected by Deep Learning
Yoshihiro Takeda, Nobunari Kashikawa, Kei Ito +12
We present spectroscopic follow-up observations with Subaru/MOIRCS of four protocluster candidate regions identified by the deep-learning model PCFNet. In three candidate regions,…
Probing Spatial Variations in IGM Transmission: Higher Ly Visibility in an H-Selected Galaxy Overdensity at
Shunta Shimizu, Nobunari Kashikawa, Junya Arita +13
The visibility of Ly emission during the epoch of reionization depends on both galaxy properties and the transmission of Ly photons through the intergalactic medium (IGM). Us…
H I Absorbers as Beacons of Hidden Structure at : Multi-Component, Metal-Rich Absorption System near a Protocluster
Kentaro Koretomo, Nobunari Kashikawa, Toru Misawa +12
H I gas traces the large-scale structure and provides the primary fuel for star formation. High- protoclusters are ideal laboratories to study how H I gas is accreted and consum…
Subaru meets JWST: A Direct Measurement of Ly Escape Fraction at with Dual Narrow-Band Imaging
Shunta Shimizu, Nobunari Kashikawa, Ryo Emori +15
We present a direct measurement of the Ly escape fraction, , for H emitters (HAEs) at in the JWST CEERS field by combining JWST/NIRCam F47…
Subaru High- Exploration of Low-Luminosity Quasars (SHELLQs). XXV. Large-scale environments of low-luminosity quasars at traced by Ly emitters
Junya Arita, Nobunari Kashikawa, Yoshiki Matsuoka +18
High- quasars are believed to reside in massive dark matter haloes (DMHs), suggesting that they reside in galaxy overdense regions. However, previous observations have shown a r…
Age dependence of Lyα escape fraction of Lyα emitters and their significant role in cosmic reionization
Shunta Shimizu, Nobunari Kashikawa, Satoshi Kikuta +4
We study the Ly escape fraction, of Ly emitters (LAEs) identified by Subaru/HSC narrowband imaging at , using publicly availabl…
