A Strong Blend in the Morning: Studying the Circumgalactic Medium Before Cosmic Noon with Strong, Blended Lyman- Forest Systems
Sean Morrison, Debopam Som, Matthew M. Pieri +2
We study of the properties of a new class of circumgalactic medium absorbers identified in the Lyman- forest: "Strong, Blended Lyman-" (or SBLA) absorption systems. We study…
The miniJPAS survey quasar selection IV: Classification and redshift estimation with SQUEzE
Ignasi Pérez-Ràfols, L. Raul Abramo, Ginés Martínez-Solaeche +24
We present a list of quasar candidates including photometric redshift estimates from the miniJPAS Data Release constructed using SQUEzE. This work is based on machine-learning clas…
3D Correlations in the Lyman- Forest from Early DESI Data
Calum Gordon, Andrei Cuceu, Jonás Chaves-Montero +56
We present the first measurements of Lyman- (Ly) forest correlations using early data from the Dark Energy Spectroscopic Instrument (DESI). We measure the auto-correlation of…
Optimal 1D Ly Forest Power Spectrum Estimation -- III. DESI early data
Naim Göksel Karaçaylı, Paul Martini, Julien Guy +59
The one-dimensional power spectrum of the Ly forest provides important information about cosmological and astrophysical parameters, including constraints on wa…
The Lyman- forest catalog from the Dark Energy Spectroscopic Instrument Early Data Release
César Ramírez-Pérez, Ignasi Pérez-Ràfols, Andreu Font-Ribera +67
We present and validate the catalog of Lyman- forest fluctuations for 3D analyses using the Early Data Release (EDR) from the Dark Energy Spectroscopic Instrument (DESI) survey.…
The Dark Energy Spectroscopic Instrument: One-dimensional power spectrum from first Lyman- forest samples with Fast Fourier Transform
Corentin Ravoux, Marie Lynn Abdul-Karim, Eric Armengaud +63
We present the one-dimensional Lyman- forest power spectrum measurement using the first data provided by the Dark Energy Spectroscopic Instrument (DESI). The data sample compris…
