Non-Gaussian statistics in galaxy weak lensing: compressed three-point correlations and cosmological forecasts
Sofia Samario-Nava, Alejandro Aviles, Juan Carlos Hidalgo
Building on previous developments of a harmonic decomposition framework for computing the three-point correlation function (3PCF) of projected scalar fields over the sky, this work…

Testing gravity with the full-shape galaxy power spectrum: first constraints on scale-dependent modified gravity
Alejandro Aviles
Since the discovery of the accelerated expansion of the Universe in 1998, modified gravity (MG) theories have attracted considerable attention as alternatives to dark energy (DE).…

Modeling the 3-point correlation function of projected scalar fields on the sphere
Abraham Arvizu, Alejandro Aviles, Juan Carlos Hidalgo +5
One of the main obstacles for the signal extraction of the three point correlation function using photometric surveys, such as the Rubin Observatory Legacy Survey of Space and Time…
