Cluster gravitational redshifts: uncertainties and survey requirements
Eleni Tsaprazi, Giorgio F. Lesci, Federico Marulli +2
We investigate the impact of observational and theoretical uncertainties in cluster gravitational redshifts as a probe of modified gravity using an end-to-end forecasting pipeline.…

Differentiable Forward Modeling for Efficient and Accurate Shear Inference
Ismael Mendoza, Axel Guinot, Matthew R. Becker +6
Forthcoming Stage-IV dark energy optical surveys, such as LSST, have the ambitious goal of measuring cosmological parameters at sub-percent precision. Realizing their full scientif…

Beyond general relativity: probing gravity with gravitational redshifts
Eleni Tsaprazi, Giorgio F. Lesci, Federico Marulli +7
Despite the success of general relativity (GR), the unexplained nature of dark energy on cosmological scales leaves open the question of whether GR provides a complete description…
