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…
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…
Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at with the 21-cm forest power spectrum
Tomáš Šoltinský, Arnab Chakraborty, Girish Kulkarni +10
Neutral regions of the intergalactic medium (IGM) during the Epoch of Reionization (EoR) remain largely unexplored due to the limitations of existing probes. Owing to discoveries o…
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…
Probing the large-scale structure with 21cm-galaxy cross-bispectrum: Estimates from simulations and forecasts for upcoming cosmological surveys
Leon Noble, Suman Majumdar, Matteo Viel +7
The paper investigates the 21 cm–galaxy cross‑bispectrum using simulated galaxy evolution models and forecasts its detectability with upcoming Euclid‑like galaxy surveys and SKA‑Mi…
Constraints on Ultra-Light Axions from the DESI DR1 Full Shape, Planck and ACT
Francesco Verdiani, Emanuele Castorina, Ennio Salvioni +2
The paper derives new limits on ultra-light axions as a small part of dark matter using galaxy clustering data from DESI DR1 together with CMB measurements from Planck and ACT.
