Kavli Affiliate: Blake Sherwin | First 5 Authors: Karen Perez Sarmiento, Alex Laguë, Mathew Madhavacheril, Bhuvnesh Jain, Blake Sherwin | Summary: We reconstruct the non-linear matter power spectrum $P(k)$ using a joint analysis of gravitational lensing of the cosmic microwave background (CMB) and lensing of galaxies. This reconstruction is motivated by the $S_8$ tension between […]
