An Attractor-Repeller model of the Local Universe : The -Szekeres spacetime and Perturbation Theory
Maharshi Sarma, Christian Marinoni, Basheer Kalbouneh
The standard linearly perturbed Friedmann-Lemaître-Robertson-Walker (FLRW) framework provides an accurate description of the Universe on large scales but cannot fully capture the n…
Gravitational entropy in Petrov Type I spacetimes
Maharshi Sarma, Sebastián Nájera, Roberto A. Sussman
The gravitational entropy proposal of Clifton, Ellis and Tavakol (CET) is based on an effective energy momentum tensor formed by the algebraic decomposition of the 4th order Bel-Ro…
Covariant cosmography in the presence of local structures: comparing exact solutions and perturbation theory
Maharshi Sarma, Christian Marinoni, Basheer Kalbouneh +2
Recent observational evidence of axially symmetric anisotropies in the local cosmic expansion rate motivates an investigation of whether they can be accounted for within the Lemaît…
The anisotropic expansion rate of the local Universe and its covariant cosmographic interpretation
Basheer Kalbouneh, Christian Marinoni, Roy Maartens +5
Without making any assumption on the underlying geometry and metric of the local Universe, we provide a measurement of the expansion rate fluctuation field using the Cosmicflows-4…
Expanding covariant cosmography of the local Universe: incorporating the snap and axial symmetry
Basheer Kalbouneh, Jessica Santiago, Christian Marinoni +3
Studies show that the model-independent, fully non-perturbative covariant cosmographic approach is suitable for analyzing the local Universe . However, accurately…
