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…
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 spe…
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…
White Dwarfs with Infrared Excess in the HET Dark Energy Experiment
Rudy A. Morales, Barbara G. Castanheira, Jayden Blanchard +5
White dwarfs with infrared excess emission provide a window into the late stages of stellar evolution and the dynamics of circumstellar environments. Using data from the Hobby-Eber…
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…
