Addressing type Ia supernova color variability with a linear spectral template
Cássia S. Nascimento, João Paulo C. França, Ribamar R. R. Reis
Type Ia Supernovae (SNeIa) provided the first evidence of an accelerated expansion of the universe and remain a valuable probe to cosmology. They are deemed standardizable candles…
Compact stars in scalar-tensor theories with a single-well potential and the corresponding theory
Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis +2
The macroscopic properties of compact stars in modified gravity theories can be significantly different from the general relativistic (GR) predictions. Within the gravitational con…
Data-driven photometric redshift estimation from type Ia supernovae light curves
Felipe M F de Oliveira, Marcelo Vargas dos Santos, Ribamar R R Reis
Redshift measurement has always been a constant need in modern astronomy and cosmology. And as new surveys have been providing an immense amount of data on astronomical objects, th…
Charged quark stars in metric gravity
Juan M. Z. Pretel, José D. V. Arbañil, Sergio B. Duarte +2
We provide the modified TOV equations for the hydrostatic equilibrium of charged compact stars within the metric gravitational background. We adopt the MIT bag model EoS for…
-gravity quark stars from perturbative QCD
José C. Jiménez, Juan M. Z. Pretel, Eduardo S. Fraga +2
We investigate the structure of quark stars in the framework of gravity using an equation of state for cold quark matter obtained from perturbative QCD, parametrize…
Influence of gravitational waves upon light in the Minkowski background: from null geodesics to interferometry
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
We have recently derived a manifestly covariant evolution law, under the geometrical optics approximation of the vacuum Maxwell's equations, for the electric field along null geode…
