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…
What can we learn about Reionization astrophysical parameters using Gaussian Process Regression?
Purba Mukherjee, Antara Dey, Supratik Pal
Reionization is one of the least understood processes in the evolution history of the Universe, mostly because of the numerous astrophysical processes occurring simultaneously abou…
Revisiting Gaussian Process Reconstruction for Cosmological Inference: The Generalised GP (Gen GP) Framework
Ruchika, Purba Mukherjee, Arianna Favale
We investigate uncertainties in the estimation of the Hubble constant () arising from Gaussian Process (GP) reconstruction, demonstrating that the choice of kernel introduces…
Interacting Dark Sectors in light of DESI DR2
Rahul Shah, Purba Mukherjee, Supratik Pal
Possible interaction between dark energy and dark matter has previously shown promise in alleviating the clustering tension, without exacerbating the Hubble tension, when Baryon Ac…
