Assessing non-linear models for galaxy clustering – II. Model validation and forecasts for Stage IV surveys
Pourtsidou, Alkistis; Bose, Benjamin; Markovic, Katarina (Oxford University Press, 2020)Accurate modelling of non-linear scales in galaxy clustering will be crucial for data analysis of Stage IV galaxy surveys. A selection of competing non-linear models must be made based on validation studies. We provide a ... -
Hybrid P` (k): General, unified, non-linear matter power spectrum in redshift space
Pourtsidou, Alkistis; Bose, Benjamin; Winther, Hans A. (IOP Publishing Ltd, 2020)Constraints on gravity and cosmology will greatly benefit from performing joint clustering and weak lensing analyses on large-scale structure data sets. Utilising non-linear information coming from small physical scales ... -
On the road to per cent accuracy - V. The non-linear power spectrum beyond ΛCDM with massive neutrinos and baryonic feedback
Bose, Benjamin; Wright, Bill S; Pourtsidou, Alkistis (Oxford University Press, 2021-12)In the context of forthcoming galaxy surveys, to ensure unbiased constraints on cosmology and gravity when using non-linear structure information, per cent-level accuracy is required when modelling the power spectrum. This ...
