Observational Constraints on Gravity from Model-Independent Data
F. B. M. dos Santos, J. E. Gonzalez, R. Silva
We establish new constraints on gravity models by using cosmological data. In particular, we investigate the restrictions given by the gas mass fraction measurements of gala…
Gravitational lens time-delay as a probe of a possible time variation of the fine-structure constant
L. R. Colaço, J. E. Gonzalez, R. F. L. Holanda
A new method based on large-scale structure observations is proposed to probe a possible time variation of the fine-structure constant (). Our analyses are based on time-delay o…
Thermodynamic Constraints on the Dark Sector
W. J. C. da Silva, J. E. Gonzalez, R. Silva +1
In this paper, we present a unified scheme based on the fluid description of the dark sector of the universe. The scheme captures models with interaction between dark energy and da…
Reconstruction of cosmological matter perturbations in Modified Gravity
J. E. Gonzalez
The analysis of perturbative quantities is a powerful tool to distinguish between different Dark Energy models and gravity theories degenerated at the background level. In this wor…
Studying the evolution of galaxies in compact groups over the past 3 Gyr - II. The importance of environment in the suppression of star formation
T. Bitsakis, D. Dultzin, L. Ciesla +9
We present an in depth study on the evolution of galaxy properties in compact groups over the past 3 Gyr. We are using the largest multi-wavelength sample to-date, comprised 1770 g…
Constructing a cosmological model-independent Hubble diagram of type Ia supernovae with cosmic chronometers
Zhengxiang Li, J. E. Gonzalez, Hongwei Yu +2
We apply two methods, namely the Gaussian processes and the non-parametric smoothing procedure, to reconstruct the Hubble parameter as a function of redshift from 15 measure…
