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 spect…
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 struc…
Cosmological Parameter Uncertainties from SALT-II Type Ia Supernova Light Curve Models
J. Mosher, J. Guy, R. Kessler +11
We use simulated SN Ia samples, including both photometry and spectra, to perform the first direct validation of cosmology analysis using the SALT-II light curve model. This valida…
Broad Absorption Line Variability on Multi-Year Timescales in a Large Quasar Sample
N. Filiz Ak, W. N. Brandt, P. B. Hall +10
We present a detailed investigation of the variability of 428 C IV and 235 Si IV Broad Absorption Line (BAL) troughs identified in multi-epoch observations of 291 quasars by the Sl…
Broad Absorption Line Disappearance on Multi-Year Timescales in a Large Quasar Sample
N. Filiz Ak, W. N. Brandt, P. B. Hall +16
We present 21 examples of C IV Broad Absorption Line (BAL) trough disappearance in 19 quasars selected from systematic multi-epoch observations of 582 bright BAL quasars (1.9 < z <…
