DESCRIPTION:Extracting the full scientific potential of the weak lensing d
 ata from Euclid and the Vera Rubin Observatory will require analysis metho
 ds that are both highly precise and maximally informative. The standard ap
 proach\, based on two-point statistics\, is effective but sub-optimal: it 
 discards information in the data and relies on simplifying assumptions in 
 the physical and statistical modelling. In this talk\, I will present a ne
 w approach to weak lensing analysis that employs a full-physics model and 
 field-level statistics. By analysing lensing maps pixel by pixel\, this me
 thod makes optimal use of the data and provides more precise cosmological 
 constraints and a map of the dark matter in the Universe. I will discuss t
 he current progress and ways to meet the challenges of this approach in it
 s first real data application.\n\nhttps://agenda.ciemat.es/event/5674/
