Towards a full $w$CDM map-based analysis for weak lensing surveys

Understand

The next generation of weak lensing surveys will measure the matter distribution of the local Universe with unprecedented precision, allowing the resolution of non-Gaussian features of the convergence field.

• This encourages the use of higher-order mass-map statistics for cosmological parameter inference.
• We extend the forward-modelling based methodology introduced in a previous forecast paper to match these new requirements.
• We provide multiple forecasts for the wCDM parameter constraints that can be expected from stage 3 and 4 weak lensing surveys.
