WIMP Freeze-Out in Diffusive Unimodular Gravity
Cesar Bonilla, Esteban Gonzalez, Carlos Maldonado
We study a non-standard cosmology (NSC) scenario within the Unimodular Gravity (UG) framework, sourced by a scalar field that undergoes energy diffusion, parametrized by the di…

FIMP Dark Matter in bulk viscous non-standard cosmologies
Esteban González, Carlos Maldonado, N. StefanÃa Mite +1
In this paper, we revisit the extension of the classical non-standard cosmological model in which dissipative processes are considered through a bulk viscous term in the new field…
