The PAU Survey: A Forward Modeling Approach for Narrow-band Imaging

Understand

Weak gravitational lensing is a powerful probe of the dark sector, once measurement systematic errors can be controlled.

• In Refregier & Amara (2014), a calibration method based on forward modeling, called MCCL, was proposed.
• This relies on fast image simulations (e.g., UFig; Berge et al.
• 2013) that capture the key features of galaxy populations and measurement effects.
