Dyonic Simpson Visser black-bounce spacetime surrounded by an exotic Einstein cluster in general relativity
Pedro Cañate, Joseph Sultana, Demosthenes Kazanas
In this work, we present the Simpson-Visser black-bounce (SV-BB) spacetime with both electric and magnetic charges (the dyonic SV-BB) as an exact solution of general relativity cou…
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…
Ghost and Laplacian Instabilities in the Teleparallel Horndeski Gravity
Salvatore Capozziello, Maria Caruana, Jackson Levi Said +1
Teleparallel geometry offers a platform on which to build up theories of gravity where torsion rather than curvature mediates gravitational interaction. The teleparallel analogue o…
Constraining f(R) models with cosmic chronometers and the HII galaxy Hubble diagram
Joseph Sultana, Manoj K. Yennapureddy, Fulvio Melia +1
We consider several well-known f(R) cosmological models and constrain their parameters, namely the deviation parameter b and the cosmological parameters Ω_m and h. We first obtain…
Neural Network Reconstruction of Late-Time Cosmology and Null Tests
Konstantinos Dialektopoulos, Jackson Levi Said, Jurgen Mifsud +2
The prospect of nonparametric reconstructions of cosmological parameters from observational data sets has been a popular topic in the literature for a number of years. This has mai…
Spatial Curvature in Gravity
Christine R. Farrugia, Joseph Sultana, Jurgen Mifsud
In this work, we consider four gravity models -- the Hu-Sawicki, Starobinsky, Exponential and Tsujikawa models -- and use a range of cosmological data, together with Markov…
