Generalized tension metrics for multiple cosmological datasets
Matías Leizerovich, Susana J. Landau, Claudia G. Scóccola
We introduce a novel estimator to quantify statistical tensions among multiple cosmological datasets simultaneously. This estimator generalizes the Difference-in-Means statistic, $…

On Geometric Cosmology
Gustavo Arciniega, Luisa G. Jaime, Susana J. Landau +1
We present a modification to General Relativity by making a redefinition of the coupling constant in front of the Ricci curvature scalar along with the Generalized Quasi-topologica…
