Revisiting the Constancy of the Speed of Light: Galaxy Cluster Mass Bias Implications
R. F. L. Holanda, Marcelo Ferreira, Javier E. Gonzalez +1
In recent years, improvements in galaxy cluster observations have enabled a variety of tests of fundamental physics using these systems. In this work, we test the constancy of the…

Observational constraints on the product of dark energy chemical potential and number density in out-of-equilibrium models
J. M. Costa Netto, Javier E. Gonzalez, H. H. B. Silva
In this work, we impose observational limits on the product of dark energy chemical potential, , and number density, , at the present time in out-of-equilibrium models, cons…

An investigation of a varying G through Strong Lensing and SNe Ia observations
R. F. L. Holanda, M. Ferreira, Javier E. Gonzalez
In this paper, we analyze the potential variation of the gravitational constant using data from strong gravitational lensing systems and Type Ia supernovae. Testing para…
