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…
Cross-correlations between the CLAMATO Lyman-alpha forest and galaxies within the COSMOS field
Benjamin Zhang, Khee-Gan Lee, Andrei Cuceu +2
We compute the 3D cross-correlation between the absorption of the Lyman-alpha forest measured by the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) su…
RIDEN pilot survey: broad-band selection of candidate quasars with extended Lyman- nebulae using CLAUDS-HSC-SSP-DUNES joint data
Rhythm Shimakawa, Satoshi Kikuta, Haruka Kusakabe +5
The Vera C. Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST), delivering deep, multi-band () imaging data across 18,000 square degrees over the nex…
Subaru High- Exploration of Low-Luminosity Quasars (SHELLQs). XXIII. The powering mechanisms of the Ly haloes around high- quasars probed by slit spectroscopy
Hiroki Hoshi, Rikako Ishimoto, Nobunari Kashikawa +15
We present the analysis of Ly haloes around faint quasars at and . We use 20 and 162 quasars at and , taken by slit spectroscopy, and detect L…
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…
The Dependence of Galaxy Properties on the Underlying 3D Matter Density Field at 2.0 < z < 2.5
Rieko Momose, Khee-Gan Lee, Benjamin Horowitz +2
We study the environmental effect of galaxy evolution as a function of the underlying 3D dark matter density for the first time at , in which the underlying matter density…
