Cosmography using strong lensing systems and cosmic chronometers
Andrés Lizardo, Mario H. Amante, Miguel A. García-Aspeitia +2
Using a new sub-sample of observed strong gravitational lens systems, for the first time, we present the equation for the angular diameter distance in the -redshift scenario for…
Dissecting the Strong-lensing Galaxy Cluster MS 0440.5+0204. I. The Mass Density Profile
Tomás Verdugo, Eleazar R. Carrasco, Gael Foëx +5
We present a parametric strong lensing modeling of the galaxy cluster MS\,0440.5+0204 (located at = 0.19). We have performed a strong lensing mass reconstruction of the cluster…
Linear perturbations spectra for dynamical dark energy inspired by modified gravity
Celia Escamilla-Rivera, A. Hernández-Almada, Miguel A. García-Aspeitia +1
In this paper, we study a particular modified gravity Equation of State, the so-called Jaime-Jaber-Escamilla, that emerges from the first gravity modified action principle and can…
Stability analysis and constraints on interacting viscous cosmology
A. Hernández-Almada, Miguel A. García-Aspeitia, Juan Magaña +1
In this work we study the evolution of a spatially flat Universe by considering a viscous dark matter and perfect fluids for dark energy and radiation, including an interaction ter…
Microlensing Analysis for the gravitational lens systems SDSS0924+0219, Q1355-2257, and SDSS1029+2623
K. Rojas, V. Motta, E. Mediavilla +3
We use spectroscopic observations of the gravitationally lensed systems SDSS0924+0219(BC), Q1355-2257(AB), and SDSS1029+2623(BC) to analyze microlensing and dust extinction in the…
