Surface Tension: Accelerated Expansion, Coincidence Problem & Hubble Tension

C. Ortiz

In this paper we give a physical explanation to the accelerated expansion of the Universe, alleviating the tension between the discrepancy of Hubble constant measurements. By the E…

A New Weyl-like Tensor of Geometric Origin

Ram Gopal Vishwakarma

A set of new tensors of purely geometric origin have been investigated, which form a hierarchy. A tensor of a lower rank plays the role of the potential for the tensor of one rank…

Relativistic potential of Weyl: a gateway to quantum physics in the presence of gravitation?

Ram Gopal Vishwakarma

The well-noted correspondence between gravitation and electrodynamics emphasizes the importance of the Lanczos tensor -- the potential of the Weyl tensor -- which is an inherent st…

Strong lensing by DHOST black holes

Javier Chagoya, C. Ortiz, Benito Rodríguez +1

The deflection of light in the strong field limit is an important test for alternative theories of gravity. However, solutions for the metric that allow for analytic computations a…

Linear perturbations spectra for dynamical dark energy inspired by modified gravity

Celia Escamilla-Rivera, A. Hernández-Almada, Miguel A. García-Aspeitia +1

In this paper, we study a particular modified gravity Equation of State, the so-called Jaime-Jaber-Escamilla, that emerges from the first gravity modified action principle and can…

Gravitational waves in braneworlds after multi-messenger events

Miguel A. García-Aspeitia, Celia Escamilla-Rivera

The GW170817 event opened a new window to test modifications to General Relativity with the aim of discard or impose strong constraints in extra dimension theories of gravity. Conc…
