HETDEX: Star Formation Stochasticity Diagram of Lyman Alpha Emitting Galaxies at Cosmic Noon Confirms Three Archetypes

Nicole Firestone, Eric Gawiser, Kartheik G. Iyer +14

In this work, we aim to measure the star formation stochasticity of Lyman Alpha Emitting Galaxies (LAEs) at Cosmic Noon. We identify 270 LAEs from the HETDEX Survey in the COSMOS f…

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…

Absorption Troughs of Lyman Alpha Emitters in HETDEX

Laurel H. Weiss, Dustin Davis, Karl Gebhardt +21

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is designed to detect and measure the redshifts of more than one million Ly emitting galaxies (LAEs) between $1.88 < z…
