Enhancing Lyα Emitter Identification in HETDEX with a Convolutional Neural Network

Shiro Mukae, Erin Mentuch Cooper, Karl Gebhardt +9

We present a deep learning framework to enhance the identification of Ly emitters (LAEs) in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), an untargeted spectroscop…

Lyα Intensity Mapping in HETDEX: Galaxy-Lyα Intensity Cross-Power Spectrum

Maja Lujan Niemeyer, Eiichiro Komatsu, José Luis Bernal +18

We present a measurement of the Lyman- (Ly) intensity mapping power spectrum from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We measure the cross-power spect…

Simulating realistic Lyman- emitting galaxies including the effect of radiative transfer

Hasti Khoraminezhad, Shun Saito, Max Gronke +1

We present an empirical yet physically motivated simulation of realistic Lyman- emitters (LAEs) at , crucial for ongoing and forthcoming cosmological LAE surveys. We c…

DESI Spectroscopy of HETDEX Emission-line Candidates I: Line Discrimination Validation

Martin Landriau, Erin Mentuch Cooper, Dustin Davis +50

The Hobby-Eberly Dark Energy Experiment (HETDEX) is an untargeted spectroscopic galaxy survey that uses Ly emitting galaxies (LAEs) as tracers of 1.9 < z < 3.5 large scale struc…

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 {…
