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…

SILVERRUSH. XIV. Lya Luminosity Functions and Angular Correlation Functions from ~20,000 Lya Emitters at z~2.2-7.3 from upto 24 HSC-SSP and CHORUS Surveys: Linking the Post-Reionization Epoch to the Heart of Reionization

Hiroya Umeda, Masami Ouchi, Satoshi Kikuta +11

We present the luminosity functions (LFs) and angular correlation functions (ACFs) derived from 18,960 Ly emitters (LAEs) at over a wide survey area of $\lesssim24 {…
