A ready-to-fit inhomogeneous cosmological model: The axially symmetric Szekeres spacetime
Marie-Noëlle Célérier
The purpose of the present work is based on two main observations: the tensions encountered by the standard CDM model when confronted to precision small scale cosmological data…
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.…

In a recent series of papers new exact analytical solutions of Einstein equations representing interior spacetimes sourced by stationary rigidly rotating cylinders of fluids have b…
Study of stationary rigidly rotating anisotropic cylindrical fluids with new exact interior solutions of GR. 3. Azimuthal pressure
Marie-Noëlle Célérier
An investigation of interior spacetimes sourced by stationary cylindrical anisotropic fluids is presented and specialized to rigidly rotating fluids with an azimuthally directed pr…
Hilbert repulsion in the Reissner-Nordström and Schwarzschild spacetimes
M. -N. Célérier, N. O. Santos, V. H. Satheeshkumar
Studying particle motion in the gravitational field of a black hole from the perspective of different observers is important for separating the coordinate artifacts from the physic…
Redshift and redshift-drift in quasi-spherical Szekeres cosmological models and the effect of averaging
Priti Mishra, Marie-Noëlle Célérier
Since the advent of the accelerated expanding homogeneous universe model, some other explanations for the supernova Ia dimming have been explored, among which there are inhomogeneo…
Redshift-drift as a test for discriminating between decelerating inhomogeneous and accelerating universe models
Priti Mishra, Marie-Noëlle Célérier, Tejinder P. Singh
Exact inhomogeneous solutions of Einstein's equations have been used in the literature to build models reproducing the cosmological data without dark energy. However, owing to the…
Effects of inhomogeneities on the expansion of the Universe: a challenge to dark energy?
Marie-Noëlle Célérier
The current standard model of cosmology, the LambdaCDM model, is based on the homogeneous FLRW solutions of the Einstein equations to which some perturbations are added to account…
Motion equations for relativistic particles in an external electromagnetic field in scale relativity
Marie-Noëlle Célérier, Laurent Nottale
Klein-Gordon and Dirac equations are the motion equations for relativistic particles with spin 0 (so-called scalar particles) and 1/2 (electron/positron) respectively. For a free p…
A (giant) void is not mandatory to explain away dark energy with a Lemaitre - Tolman model
Marie-Noëlle Célérier, Krzysztof Bolejko, Andrzej Krasiński
Lemaître - Tolman (L--T) toy models with a central observer have been used to study the effect of large scale inhomogeneities on the SN Ia dimming. Claims that a giant void is mand…
Scaling Regimes as obtained from the DR5 Sloan Digital Sky Survey
Reuben Thieberger, Marie-Noëlle Célérier
Standard cosmology is based on the assumption that the universe is spatially homogeneous. However the consensus on a homogeneous matter structure, even on very large scales, has ne…
Quantum-classical transition in Scale Relativity
Marie-Noëlle Célérier, Laurent Nottale
The theory of scale relativity provides a new insight into the origin of fundamental laws in physics. Its application to microphysics allows us to recover quantum mechanics as mech…
Non-Abelian gauge field theory in scale relativity
Laurent Nottale, Marie-Noëlle Célérier, Thierry Lehner
Gauge field theory is developed in the framework of scale relativity. In this theory, space-time is described as a non-differentiable continuum, which implies it is fractal, i.e.,…
Relativistic corrections to fractal analyses of the galaxy distribution
Marie-Noëlle Célérier, Reuben Thieberger
The effect of curvature on the results of fractal analyses of the galaxy distribution is investigated. We show that, if the universe satisfies the criteria of a wide class of parab…
Solving the horizon problem with a Delayed Big-Bang singularity
Marie-Noëlle Célérier
The hot Big-Bang standard model for the evolution of the universe, despite strong successes, lets unresolved a number of problems. One of its main drawbacks, known as the horizon p…
