Close Hyperbolic Encounters In f(R) Gravity

Jenna Bruton, Peter Dunsby, Alvaro de la Cruz-Dombriz

We explore the dynamics and gravitational-wave emission from black hole pairs on unbound orbits undergoing close hyperbolic encounters (CHEs) in dense astrophysical environments. W…

Toward a realistic Buchdahl limit in f(R) theories of gravity

Raul Carpio Fernandez, Alvaro de la Cruz-Dombriz

The so-called Buchdahl limit is not yet fully understood in the context of theories of gravity beyond the Einsteinian framework. In this investigation, we generalize this limit for…

Imprint of f(R) gravity in the cosmic magnification

Didam Duniya, Amare Abebe, Alvaro de la Cruz-Dombriz +1

f(R) gravity is one of the simplest viable modifications to General Relativity: it passes local astrophysical tests, predicts both the early-time cosmic inflation and the late-time…

Focusing conditions for extended teleparallel gravity theories

U. K. Beckering Vinckers, A. de la Cruz-Dombriz, F. J. Maldonado Torralba

In the context of extended theories of teleparallel gravity we derive the focusing conditions for a one-parameter dependent congruence of timelike auto-parallels of the Levi…

Improvements in cosmological constraints from breaking growth degeneracy

Louis Perenon, Stéphane Ilić, Roy Maartens +1

The key probes of the growth of large-scale structure are its rate and amplitude . Redshift space distortions in the galaxy power spectrum allow us to measure only the com…

Scalar perturbations in gravity using the covariant approach

Shambel Sahlu, Joseph Ntahompagaze, Amare Abebe +2

The cosmological scalar perturbations of standard matter are investigated in the context of extended teleparallel gravity theories using the covariant formalism. After…
