Physical Calibration of a Minimal Effective Field Theory of the Three-Dimensional Lyman- Forest
Gabriele Autieri, Vid Iršič, Tomáš Šoltinsky +1
We study a minimal effective field theory description of the three-dimensional Lyman- forest using the Sherwood and Sherwood--Relics hydrodynamical simulations. We model the Lym…
Estimation of distribution functions, their jumps and interval probabilities under measurement error
Kairat Mynbaev, Carlos Martins-Filho, Chad Brown
We consider the classical additive measurement-error model , where the latent random variable has unknown distribution and the error has a known distribution.…
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…
Ringing of the Reionization: A first direct measurement of the intergalactic pressure smoothing scale at redshift z>4.2 as imprinted onto small-scale peculiar velocities in the Lyman-alpha forest
Vid IrÅ¡iÄ, Matteo Viel, Martin G. Haehnelt +3
The epoch of reionization leaves detectable imprints in the thermal history of the Universe. In particular, the fast ionization fronts passing over cold gas in the cosmic web overp…
High resolution Lyman-α forest constraints on dark matter-neutrino scattering
Markus R. Mosbech, Olga Garcia-Gallego, Vid IrÅ¡iÄ +2
The paper uses high‑resolution Lyman‑α forest data and a suite of hydrodynamical simulations to place the strongest direct limits to date on dark matter–neutrino scattering, findin…
Small-scale Lyman alpha forest cosmology with PRIYA: Constraints from XQ100 and KODIAQ-SQUAD one-dimensional flux power spectra
Ming-Feng Ho, Mahdi Qezlou, Simeon Bird +4
We present a new cosmological analysis of the small-scale Lyman alpha forest 1D flux power spectrum (P1D) using high-resolution quasar spectra from XQ100 and KODIAQ-SQUAD, interpre…
