From Dark Radiation to Dark Energy: Unified Cosmological Evolution in K-essence Models
Eladio Moreno, Josue De-Santiago
We study a class of Unified Dark Matter (UDM) models based on generalized K-essence, where a single scalar field with non-canonical kinetic terms accounts for dark radiation, dark…

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…
