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…

Radio-detected Lya emitters at 1.88 < z < 3.52: AGN fraction and Lya emission

Sai Zhai, Huub Röttgering, Anniek J. Gloudemans +10

Lya emitters (LAEs) are galaxies with strong Lya emission, tracing early star formation and ionizing radiation. Their connection to active galactic nuclei (AGNs) is key to understa…

HETDEX [OII] galaxies at : Volume-limited samples and their power spectra

Jeongin Moon, Eiichiro Komatsu, Robin Ciardullo +15

The catalog from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Public Data Release 1 (PDR1) contains half a million emission-line-selected [OII] galaxies spread across…

Extended Structure in E+A Galaxies Via Image Stacking

Kieran Broadbelt, Kevin Pimbblet, Daniel Farrow +1

Small-scale interactions such as minor mergers, flybys and harassment are considered common driving mechanisms that can both initiate and quench star-forming processes within post-…

HETDEX Public Data Release 1: Source Catalog 2 and Data Cubes from ~90 sq deg of Integral-Field Optical Spectroscopy

Erin Mentuch Cooper, Karl Gebhardt, Dustin Davis +36

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a wide-field, integral-field spectroscopic survey designed to map the large-scale distribution of Lyman-alpha emitting…

Golden and Silver Dark Sirens for precise H0 measurement with HETDEX

Yixuan Dang, Ish Gupta, Robin Ciardullo +12

Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source's luminosity distance, enabling an independent measuremen…
