Impact of blending on weak lensing measurements with the Legacy Survey of Space and Time
Manon Ramel, Cyrille Doux, Marine Kuna
Upcoming deep optical surveys, such as the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), will scan the sky to unprecedented depths, detecting billions of galaxi…
Understanding posterior projection effects with normalizing flows
Marco Raveri, Cyrille Doux, Shivam Pandey
Many modern applications of Bayesian inference, such as in cosmology, are based on complicated forward models with high-dimensional parameter spaces. This considerably limits the s…

Manon Ramel, Cyrille Doux, Marine Kuna
Upcoming deep optical surveys such as the Vera C. Rubin Observatory Legacy Survey of Space and Time will scan the sky to unprecedented depths and detect billions of galaxies. This…
What does a cosmological experiment really measure? Covariant posterior decomposition with normalizing flows
Tara Dacunha, Marco Raveri, Minsu Park +2
We present methods to rigorously extract parameter combinations that are constrained by data from posterior distributions. The standard approach uses linear methods that apply to G…
Non-Gaussian estimates of tensions in cosmological parameters
Marco Raveri, Cyrille Doux
We discuss how to efficiently and reliably estimate the level of agreement and disagreement on parameter determinations from different experiments, fully taking into account non-Ga…
