Primordial black hole production in scalar field inflation within gravity
Daniel Villalobos-Silva, Yerko Vásquez, Giovanni Otalora
We investigate inflation in modified teleparallel gravity within a scalar-tensor framework. We focus on two viable extensions of the Teleparallel Equivalent of General Relativity:…

Dynamical system analysis and observational constraints of cosmological models in mimetic gravity
Alberto Fritis, Daniel Villalobos-Silva, Yerko Vásquez +2
We study the dynamics of homogeneous and isotropic Friedmann-Lemaître-Robertson-Walker cosmological models with positive spatial curvature within the context of mimetic gravity the…
