Project Roadmap

[EiffL]

This issue is to track the roadmap of the project and centralize tasks and TODOs.

• Original project proposal

Phase I: Setting up basic forward model

In this first phase of the project we will aim to implement a given forward model, potentially using different implementations (e.g. karma, BORG, FlowPM).

• Prototype forward modelling framework #8
• Matter power spectrum as function of cosmology (most likely emulator, or E.H.) #2
• Galaxy bias model #3
• Intrinsic Alignment #4
• Tomographic redshift distributions and systematics parameterisation #5
• Survey emulation (e.g. masks, number density of lensing and clustering samples etc.) #6

Our goal in this first phase is to be able to generate realizations of a given field.

Phase II: Demonstrating cosmological inference

In the second phase of the project, we want to be able to obtain posterior on cosmological parameters from the forward models established in the previous phase.
