Diverse Metallicities in Protoclusters at $z \sim 3.4$ 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 $α$ Visibility in an H $α$ -Selected Galaxy Overdensity at $z ≃ 6.2$

Shunta Shimizu, Nobunari Kashikawa, Junya Arita +13

The visibility of Ly $α$ emission during the epoch of reionization depends on both galaxy properties and the transmission of Ly $α$ photons through the intergalactic medium (IGM). Us…

Subaru meets JWST: A Direct Measurement of Ly $α$ Escape Fraction at $z ≃ 6.2$ with Dual Narrow-Band Imaging

Shunta Shimizu, Nobunari Kashikawa, Ryo Emori +15

We present a direct measurement of the Ly $α$ escape fraction, $f_{esc}^{Ly α}$ , for H $α$ emitters (HAEs) at $z ≃ 6.2$ in the JWST CEERS field by combining JWST/NIRCam F47…
