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…
Gravitational Wave Propagation and Polarizations in the Teleparallel analog of Horndeski Gravity
Sebastian Bahamonde, Maria Caruana, Konstantinos F. Dialektopoulos +5
Gravitational waves (GWs) have opened a new window on fundamental physics in a number of important ways. The next generation of GW detectors may reveal more information about the p…
Gravitational analog of the canonical acoustic black hole in Einstein-scalar-Gauss-Bonnet theory
Pedro Cañate, Joseph Sultana, Demosthenes Kazanas
In this work, in the context of modified gravity, a curved spacetime analogous to the "canonical acoustic black hole" is constructed. The source is a self-interacting scalar field…
Reconstructing teleparallel gravity with cosmic structure growth and expansion rate data
Jackson Levi Said, Jurgen Mifsud, Joseph Sultana +1
In this work, we use a combined approach of Hubble parameter data together with redshift-space-distortion data, which together are used to reconstruct the teleparallel gra…
