Lyman Break Galaxy selection and redshift measurement with supervised contrastive learning
J. Choppin de Janvry, C. Yèche, Arjun Dey +55
Some of the next steps for high-precision cosmology lie within the high-redshift, high-density universe. Spectroscopic survey experiments such as the Dark Energy Spectroscopic Inst…
Cosmological neutrino mass: a frequentist overview in light of DESI
D. Chebat, C. Yèche, E. Armengaud +51
We derive constraints on the neutrino mass using a variety of recent cosmological datasets, including DESI BAO, the full-shape analysis of the DESI matter power spectrum and the on…
The Lyman- Forest from LBGs: First 3D Correlation Measurement with DESI and Prospects for Cosmology
Hiram K. Herrera-Alcantar, Eric Armengaud, Christophe Yèche +50
The Lyman- (Ly) forest is a key tracer of large-scale structure at redshifts z > 2, traditionally studied using spectra of quasars. Here, we explore the viability Lyman Break…
The effects of continuum fitting on Lyman- forest correlations
Nicolas Busca, James Rich, Julian Bautista +42
Correlations of fluctuations of the flux in Lyman- forests of high-redshift quasars have been observed by the Baryonic Acoustic Oscillation Spectroscopy Survey (BOSS) and the Da…
Model-Independent Measurement of the Matter-Radiation Equality Scale in DESI 2024
B. Bahr-Kalus, D. Parkinson, K. Lodha +52
The peak of the matter power spectrum, known as the turnover (TO) scale, is determined by the horizon size at the time of matter-radiation equality. This scale can serve as a stand…
Extended Dark Energy analysis using DESI DR2 BAO measurements
K. Lodha, R. Calderon, W. L. Matthewson +122
We conduct an extended analysis of dark energy constraints, in support of the findings of the DESI DR2 cosmology key paper, including DESI data, Planck CMB observations, and three…
