The cross-correlation of galaxies in absorption with the Lyman forest
Ignasi Pérez-Ràfols, Matthew M. Pieri, Michael Blomqvist +3
We present the first clustering measurement of Strong Blended Lyman (SBLA) absorption systems by measuring their cross-correlation with the Lyman forest. SBLAs are a new po…
Constraints on the cosmic expansion rate at redshift 2.3 from the Lyman- forest
Andrei Cuceu, Andreu Font-Ribera, Seshadri Nadathur +2
We determine the product of the expansion rate and angular-diameter distance at redshift from the anisotropy of Lyman- (Ly) forest correlations measured by the Sloan…
The Alcock-Paczyński effect from Lyman- forest correlations: Analysis validation with synthetic data
Andrei Cuceu, Andreu Font-Ribera, Paul Martini +6
The three-dimensional distribution of the Ly forest has been extensively used to constrain cosmology through measurements of the baryon acoustic oscillations (BAO) scale. Howeve…
Direct cosmological inference from three-dimensional correlations of the Lyman- forest
Francesca Gerardi, Andrei Cuceu, Andreu Font-Ribera +2
When performing cosmological inference, standard analyses of the Lyman- (Ly) three-dimensional correlation functions only consider the information carried by the distinct pea…
Overview of the Instrumentation for the Dark Energy Spectroscopic Instrument
B. Abareshi, J. Aguilar, S. Ahlen +264
The Dark Energy Spectroscopic Instrument (DESI) has embarked on an ambitious five-year survey to explore the nature of dark energy with spectroscopy of 40 million galaxies and quas…
