Strong lensing modeling in galaxy clusters as a promising method to test cosmography I. Parametric dark energy models
Juan Magana, Ana Acebron, Veronica Motta +3
In this paper we probe five cosmological models for which the dark energy equation of state parameter, , is parameterized as a function of redshift using strong lensing data…
Falsifying cosmological models based on a non-linear electrodynamics
Ali Övgün, Genly Leon, Juan Magaña +1
Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover,…
The Cardassian expansion revisited: constraints from updated Hubble parameter measurements and Type Ia Supernovae data
Juan Magana, Mario H. Amante, Miguel A. Garcia-Aspeitia +1
Motivated by an updated compilation of observational Hubble data (OHD) which consist of 51 points in the redshift range 0.07<z<2.36, we study an interesting model known as Cardassi…
Testing cosmic acceleration for parameterizations using measurements in galaxy clusters
Juan Magana, V. Motta, Victor H. Cardenas +1
In this paper we study the cosmic acceleration for five dynamical dark energy models whose equation of state varies with redshift. The cosmological parameters of these models are c…
