HI Simulations for Cosmology with the SKA Observatory
Tommaso Ronconi, Gabriella De Lucia, Marta Spinelli +15
We present a comparative overview of state-of-the-art methods for modelling the distribution of neutral hydrogen (HI) in the post-reionization Universe, developed in preparation fo…
Primary Beam Chromaticity in HIRAX: I. Characterization from Simulations and Power Spectrum Implications
Ajith Sampath, Devin Crichton, Kavilan Moodley +15
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is an upcoming radio interferometric telescope designed to constrain dark energy through the 21cm intensity mapping…
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…
Karabo: A versatile SKA Observation Simulation Framework
Rohit Sharma, Simon Felix, Luis Fernando Machado Poletti Valle +12
Karabo is a versatile Python-based software framework simplifying research with radio astronomy data. It bundles existing software packages into a coherent whole to improve the eas…
