Cosmological constraining power of the redshifts, heights, and angular clustering of weak gravitational lensing peaks
Jeger C. Broxterman, Matthieu Schaller, Ian G. McCarthy +8
Weak gravitational lensing (WL) peaks probe non-Gaussian information of the large-scale distribution of matter that is not captured by two-point lensing statistics. We study the co…
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…
Validation of the DESI DR2 Ly forest full-shape analysis
M. Herbold, A. Cuceu, P. Martini +107
The paper validates the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 analysis of the Lyman‑α forest, focusing on extracting the Alcock‑Paczynski (AP) measurement from…
DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +164
The DESI DR2 analysis measures the Alcock‑Paczynski effect using the full shape of Lyman‑α forest auto‑ and cross‑correlations, achieving 1% precision at redshift 2.33 and providin…
How massive neutrinos reshape the cosmic web
Leonor N. L. Simões, Krishna Naidoo, Benjamin Joachimi +2
We explore the effects of massive neutrinos on the cosmic web using the FLAMINGO simulations. We classify the cosmic web into voids, sheets, filaments, and clusters, and find that…
