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 observatio…
Reconstructing the Inflaton Potential: Primordial Black Holes and Gravitational Waves in Slow Roll and Ultra Slow Roll Single Field Inflation
Gabriele Autieri, Michele Redi
We present new single field inflationary scenarios that produce the critical abundance of primordial black holes as dark matter reconstructing the inflaton potential from an input…
