Spec-S5: A Next-Generation All-Sky Spectroscopic Facility Enabling Large-Scale Surveys for Cosmology and Astrophysics
Claire Poppett, David J. Schlegel, Arjun Dey +8
The Stage-5 Spectroscopic Experiment (Spec-S5) is a next-generation, all-sky spectroscopic facility designed to address fundamental questions in cosmology and astrophysics. Buildin…
Luminosity function of quasars at from SDSS and DESI
Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54
We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
Lyman- forest holography: 3D predictions from 1D measurements
J. Chaves-Montero, A. Font-Ribera, J. Aguilar +68
The paper introduces ForestFlow, an emulator that connects one‑dimensional Lyman‑α forest flux power spectrum measurements to three‑dimensional clustering predictions, enabling com…
CoLoRe-2LPT: Lyman- mock catalogues for the validation of DESI cosmological analyses
M. F. Ruiz-Herrera Bernal, S. Avila, A. Font-Ribera +90
The paper presents fast Lyman‑α forest mock catalogues generated with second‑order Lagrangian perturbation theory (2LPT) that accurately reproduce small‑scale clustering, BAO broad…
Probing the matter-dominated expansion with multi-redshift Lyman- BAO from DESI DR2
Hiram K. Herrera-Alcantar, Julien Guy, Alma X. Gonzalez-Morales +60
We present a multi-redshift Baryon Acoustic Oscillations (BAO) analysis of the DESI Data Release 2 (DR2) Lyman- (Ly) forest, splitting the forest auto-correlation and its c…
The DESI DR1 Peculiar Velocity Survey: growth rate measurements from galaxy and momentum correlation functions
R. J. Turner, C. Blake, F. Qin +61
Joint analysis of the local peculiar velocity and galaxy density fields offers a promising route to testing cosmological models of gravity. We present a measurement of the normalis…
