Population III Host Candidates at : Strong He II and Absent UV Metal Lines in HETDEX Ly Emitters
Mahan Mirza Khanlari, Dustin Davis, Karl Gebhardt +15
Population III (Pop III) stars are expected to produce extremely hard ionizing spectra, yet direct evidence for their signature--strong narrow He II emission with wea…
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…
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…
Emission-line Variable Active Galactic Nuclei at Cosmic Noon from HETDEX
Chenxu Liu, Fanchuan Kong, Erin Mentuch Cooper +11
We present the first statistical census of emission-line variable active galactic nuclei (EVA) at cosmic noon by combining untargeted and deep HETDEX spectroscopy with multi-epoch…
Lyα Nebulae in HETDEX: The Largest Statistical Census Bridging Lyα Halos and Blobs across Cosmic Noon
Erin Mentuch Cooper, Karl Gebhardt, Dustin Davis +20
The Hobby-Eberly Dark Energy Experiment (HETDEX) is an untargeted ~540 deg^2 spectroscopic survey of Lyα emission in the 1.9 < z < 3.5 Universe. In surface brightness, this survey…
Using Lyman Alpha Absorption to Measure the Intensity and Variability of Ultraviolet Background Light
Laurel H. Weiss, Karl Gebhardt, Dustin Davis +11
We present measurements of ultraviolet background light using Lya absorption from galaxies at in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX…
The Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX) Active Galactic Nuclei Catalog: the Fourth Data Release
Chenxu Liu, Karl Gebhardt, Erin Mentuch Cooper +7
We present the Active Galactic Nuclei (AGN) catalog from the fourth data release (HDR4) of the Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX). HETDEX is an untargete…
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…
The Pre-explosion Environments and The Progenitor of SN 2023ixf from the Hobby Eberly Telescope Dark Energy Experiment (HETDEX)
Chenxu Liu, Xinlei Chen, Xinzhong Er +20
Supernova (SN) 2023ixf was discovered on May 19th, 2023. The host galaxy, M101, was observed by the Hobby Eberly Telescope Dark Energy Experiment (HETDEX) collaboration over the pe…
ALMA gas-dynamical mass measurement of the supermassive black hole in the red nugget relic galaxy PGC 11179
Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh +10
We present 0-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO(21) emission from the circumnuclear gas disk in the red nu…
