Gravitational Wave Modeling of White-Dwarf--Compact-Object Binaries and Observational Outlook
Tristan S. Weaver, David Radice, Donghui Jeong +1
We investigate the end stages of circular white-dwarf--compact-object binaries by developing a novel integrator implementing mass transfer and 2.5-order Post-Newtonian kinematics.…
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…
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…
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 stru…
Large-Scale-Structure Observables in General Relativity Validated at Second Order
Antoine Villey, Yonadav Barry Ginat, Vincent Desjacques +2
We present a second-order calculation of relativistic large-scale-structure observables in cosmological perturbation theory, specifically the "cosmic rulers and clock", which are t…
