Investigating a Possible Variation of the Gravitational Constant Through Gas Mass Fraction Measurements and Type Ia Supernovae Observations
L. R. Colaço, R. F. L. Holanda, Marcelo Ferreira
In this paper, we investigate a possible time variation of the gravitational constant (G) using a non-parametric approach. Our main cosmological probe is the gas mass fraction of g…
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…
Non-parametric reconstruction of the fine structure constant with galaxy clusters
Marcelo Ferreira, Rodrigo F. L. Holanda, Javier E. Gonzalez +2
Testing possible variations in fundamental constants of nature is a crucial endeavor in observational cosmology. This paper investigates potential cosmological variations in the fi…
