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…
Generating all-sky radio continuum clustering simulations with GHOST
Brandon Venville, Anna Bonaldi, David Parkinson +3
Techniques using multiple tracers of the large scale structure of the universe show great promise for examining the fundamentals of our Universe's cosmology. Such techniques rely o…
SKA-Low simulations for a cosmic dawn/epoch of reionisation deep field
Anna Bonaldi, Philippa Hartley, Simon Purser +7
We present a realistic simulation of an SKA-Low cosmic dawn/epoch of reionisation (CD/EoR) observation, which can be used to further the development of foreground-mitigation approa…
Galactic foreground constraints on primordial -mode detection for ground-based experiments
Carlos Hervías-Caimapo, Anna Bonaldi, Michael L. Brown +1
Contamination by polarized foregrounds is one of the biggest challenges for future polarized cosmic microwave background (CMB) surveys and the potential detection of primordial …
SuperCLASS -- III. Weak lensing from radio and optical observations in Data Release 1
Ian Harrison, Michael L. Brown, Ben Tunbridge +17
We describe the first results on weak gravitational lensing from the SuperCLASS survey: the first survey specifically designed to measure the weak lensing effect in radio-wavelengt…
Cosmology with Phase 1 of the Square Kilometre Array; Red Book 2018: Technical specifications and performance forecasts
Square Kilometre Array Cosmology Science Working Group, David J. Bacon, Richard A. Battye +44
We present a detailed overview of the cosmological surveys that will be carried out with Phase 1 of the Square Kilometre Array (SKA1), and the science that they will enable. We hig…
