The impact of the IGM thermal state on the Ly flux 3D power spectrum from linear to highly non-linear scales
Tomáš Šoltinský, Gabriele Autieri, Vid Iršič +1
Recently initiated and upcoming spectroscopic surveys, such as DESI and WST, will provide more than high- quasar spectra, enabling dense sky coverage by the Ly forest.…
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…
Cosmology with HI Intensity Mapping
Laura Wolz, Gabriele Autieri, José Luis Bernal +18
The redshifted spectral emission from neutral hydrogen (HI) at rest wavelength 21 cm can be used as a tracer of large-scale structure and its evolution. Within the HI intensity map…
meer21cm: an Analysis Pipeline and Comprehensive Toolkit for HI Intensity Mapping
Zhaoting Chen, Steven Cunnington, Daniel Tassie +23
We present meer21cm, a comprehensive python package for cosmological data analysis of single-dish HI intensity mapping surveys. This package is simple to use, with a modularised co…
Weighing neutrinos with 21cm Intensity Mapping at the SKAO
Gabriele Autieri, Maria Berti, Marta Spinelli +2
We explore the constraining power of future 21cm intensity mapping (IM) observations at the SKAO, focusing primarily on the sum of neutrino masses, . We forecast observations…
