Cosmological Dynamics of a Non-Canonical Generalised Brans-Dicke Theory
Matthew Debono, Jackson Levi Said, Gabriel Farrugia
The LCDM model has been presented with a number of cosmic tensions in the face of precision cosmological data, suggesting the presence of a dynamical dark energy component. In this…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
White Dwarf Envelops and Temperature Corrections in Exponential Gravity
Gabriel Farrugia, Carlos Gafa', Jackson Levi Said
Compact stars have long served as a test bed of gravitational models and their coupling with stellar matter. In this work, we explore the behavior of an exponential model in f(T) g…
Spatial Dependence of the Growth Factor in Scalar-Tensor Cosmology
Maria Caruana, Gabriel Farrugia, Jackson Levi Said +1
Scalar-tensor theories have taken on a key role in attempts to confront the growing open questions in standard cosmology. It is important to understand entirely their dynamics at p…
Cosmic Growth in Teleparallel Gravity
Salvatore Capozziello, Maria Caruana, Gabriel Farrugia +2
Physical evolution of cosmological models can be tested by using expansion data, while growth history of these models is capable of testing dynamics of the inhomogeneous parts of e…
Teleparallel Gravity: From Theory to Cosmology
Sebastian Bahamonde, Konstantinos F. Dialektopoulos, Celia Escamilla-Rivera +7
Teleparallel gravity has significantly increased in popularity in recent decades, bringing attention to Einstein's other theory of gravity. In this Review, we relate this form of g…
Cosmological bouncing solutions in f(T,B) gravity
Maria Caruana, Gabriel Farrugia, Jackson Levi Said
Teleparallel Gravity offers the possibility of reformulating gravity in terms of torsion by exchanging the Levi-Civita connection with the Weitzenböck connection which describes to…
Gravitoelectromagnetism, Solar System Test and Weak-Field Solutions in Gravity with Observational Constraints
Gabriel Farrugia, Jackson Levi Said, Andrew Finch
Gravitomagnetism characterize phenomena in the weak field limit within the context of rotating systems. These are mainly manifested in the geodetic and Lense-Thirring effects. The…
Polarization of gravitational waves in symmetric teleparallel theories of gravity and their modifications
Ismail Soudi, Gabriel Farrugia, Viktor Gakis +2
Symmetric teleparallel gravity (STG) offers an interesting avenue to formulate a theory of gravitation that relies neither on curvature nor torsion but only on non-metricity Q. Giv…
Gravitational Waves in Modified Teleparallel Theories
Gabriel Farrugia, Jackson Levi Said, Viktor Gakis +1
We investigate the gravitational waves and their properties in various modified teleparallel theories, such as and gravities. We perform the perturbation…
Cosmological bouncing solutions in extended teleparallel gravity theories
Alvaro de la Cruz-Dombriz, Gabriel Farrugia, Jackson Levi Said +1
In the context of extended Teleparallel gravity theories with a 3+1 dimensions Gauss-Bonnet analog term, we address the possibility of these theories reproducing several well-known…
Some aspects of reconstruction using a scalar field in f (T ) Gravity
Soumya Chakrabarti, Jackson Levi Said, Gabriel Farrugia
General relativity characterizes gravity as a geometric property exhibited on spacetime by massive objects while teleparallel gravity achieves the same results, at the level of equ…
Cosmological reconstructed solutions in extended teleparallel gravity theories with a teleparallel Gauss-Bonnet term
Alvaro de la Cruz-Dombriz, Gabriel Farrugia, Jackson Levi Said +1
In the context of extended Teleparallel gravity theories with a 3+1 dimensions Gauss-Bonnet analog term, we address the possibility of these theories reproducing several well-known…
Stability of the flat FLRW metric in gravity
Gabriel Farrugia, Jackson Levi Said
In this paper, we investigate the stability of the flat FLRW metric in gravity. This is achieved by analysing the small perturbations, about the Hubble parameter and the…
Growth factor in gravity
Gabriel Farrugia, Jackson Levi Said
We investigate the growth factor for sub-horizon modes during late times in gravity, where is the torsion scalar and is the trace of the stress…
Solar System tests in gravity
Gabriel Farrugia, Jackson Levi Said, Matteo Luca Ruggiero
We investigate the four solar system tests of gravity - perihelion precession, light bending, Shapiro time delay, gravitational redshift - in gravity. In particular, we inve…
