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 $α$ escape fraction, $f_{esc}^{Ly α}$ of Ly $α$ emitters (LAEs) identified by Subaru/HSC narrowband imaging at $z = 2.2 - 6.6$ , using publicly availabl…

Subaru High- $z$ Exploration of Low-Luminosity Quasars (SHELLQs). XXIII. The powering mechanisms of the Ly $α$ haloes around high- $z$ quasars probed by slit spectroscopy

Hiroki Hoshi, Rikako Ishimoto, Nobunari Kashikawa +15

We present the analysis of Ly $α$ haloes around faint quasars at $z \sim 4$ and $z \sim 6$ . We use 20 and 162 quasars at $z \sim 4$ and $z \sim 6$ , taken by slit spectroscopy, and detect Ly…

Predicting Ly $α$ Emission from Distant Galaxies with Neural Network Architecture

Takehiro Yoshioka, Nobunari Kashikawa, Yoshihiro Takeda +7

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