Axio-Dilaton Dark Energy: A Dynamical Systems and Bayesian Inference Analysis
Mario Ramos-Hamud, Gabriela García-Arroyo, Fernando Quevedo +1
We initiate a systematic cosmological investigation of an axio-dilaton system governed by a curved field-space metric as generically motivated by supergravity and string compactifi…

Cosmological Constraints on Interacting Scalar-Field Dark Matter and Early Dark Energy mediated by a Kinetic Kernel
Gabriela Garcia-Arroyo, L. Arturo Ureña-López, J. Alberto Vázquez
In this work, we build a general framework for constraining interacting scalar fields with cosmological observations, applicable to a broad family of scalar--field potentials and i…
