Reconstructing Mimetic Cosmology
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +1
We explore the mimetic gravity formulation with the inclusion of a scalar field potential namely, . However, we are not considering any {\it a priori} specific form this term…
Cosmic expansion with matter creation and bulk viscosity
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
We explore the cosmological implications at effective level of matter creation effects in a dissipative fluid for a FLRW geometry; we also perform a statistical analysis for this k…
Non-zero torsion and late cosmology
Miguel Cruz, Fernando Izaurieta, Samuel Lepe
In this work, we study some thermodynamical aspects associated with torsion in a flat FLRW spacetime cosmic evolution. By implementing two Ansatze for the torsion term, we find tha…
Challenging matter creation models in the phantom divide
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +2
We perform a study both statistical and theoretical for cosmological models of matter creation and their ability to describe effective phantom models of dark energy. Such models ar…
Hamilton-Jacobi approach for Regge-Teitelboim cosmology
Alejandro Aguilar-Salas, Alberto Molgado, Efrain Rojas
The Hamilton-Jacobi formalism for a geodetic brane-like universe described by the Regge-Teitelboim model is developed. We focus on the description of the complete set of Hamiltonia…
Neutron and quark stars: constraining the parameters for simple EoS using the GW170817
Griselda Arroyo-Chávez, Alejandro Cruz-Osorio, F. D. Lora-Clavijo +2
It is well known that the equation of state (EoS) of compact objects like neutron and quark stars is not determined despite there are several sophisticated models to describe it. F…
