11. First measurement of the Weyl potential evolution from DES Y3 data

Isaac Tutusaus (IRAP-OMP)

6/10/24, 3:10 PM

In this talk I will present a new methodology to measure the Weyl potential, which is the sum of the spatial and temporal distortions of the Universe's geometry, in a model independent way. I will then present how combining galaxy clustering and galaxy-galaxy lensing data from DES Y3 we can provide the first direct measurement of the evolution of the Weyl potential at four different redshifts....
