Forecasting a Cosmological 21 cm Stacking Detection with Early HIRAX Data
Pascal Hitz, Devin Crichton, Alexandre Refregier
Post-reionization 21 cm intensity mapping provides a powerful technique for efficiently mapping the Universe on large scales. The Hydrogen Intensity and Real-time Analysis eXperime…
Fast Simulation of Cosmological Neutral Hydrogen based on the Halo Model
Pascal Hitz, Pascale Berner, Devin Crichton +2
Cosmological neutral hydrogen (HI) surveys provide a promising tomographic probe of the post-reionization era and of the standard model of cosmology. Simulations of this signal are…
3DEX: a code for fast spherical Fourier-Bessel decomposition of 3D surveys
B. Leistedt, A. Rassat, A. Refregier +1
High-precision cosmology requires the analysis of large-scale surveys in 3D spherical coordinates, i.e. spherical Fourier-Bessel decomposition. Current methods are insufficient for…
