We use the Szekeres inhomogeneous relativistic models in order to fit supernova combined data sets. We show that with a choice of the spatial curvature function that is guided by current observations, the models fit the supernova data almost as well as the LCDM model without requiring a dark energy component. The Szekeres models were originally derived as an exact solution to Einstein's equations with a general metric that has no symmetries and are regarded as good candidates to model the true…

The cosmic microwave background in an inhomogeneous universe

The dimming of Type Ia supernovae could be the result of Hubble-scale inhomogeneity in the matter and spatial curvature, rather than signaling the presence of a dark energy component. A key challenge

Observational constraints on inhomogeneous cosmological models without dark energy

It has been proposed that the observed dark energy can be explained by the effect of large-scale nonlinear inhomogeneities. In this paper, we discuss how observations constrain cosmological models

Rendering dark energy void

Dark energy observations may be explained within general relativity using an inhomogeneous Hubble-scale depression in the matter density and accompanying curvature, which evolves naturally out of an

Luminosity distance and redshift in the Szekeres inhomogeneous cosmological models

The Szekeres inhomogeneous models can be used to model the true lumpy universe that we observe. This family of exact solutions to Einstein's equations was originally derived with a general metric

Growth of structure in the Szekeres class-II inhomogeneous cosmological models and the matter-dominated era

This study belongs to a series devoted to using the Szekeres inhomogeneous models in order to develop a theoretical framework where cosmological observations can be investigated with a wider range of

The effects of structure anisotropy on lensing observables in an exact general relativistic setting for precision cosmology

The study of relativistic, higher order, and nonlinear effects has become necessary in recent years in the pursuit of precision cosmology. We develop and apply here a framework to study gravitational

Large-scale growth evolution in the Szekeres inhomogeneous cosmological models with comparison to growth data

We use the Szekeres inhomogeneous cosmological models to study the growth of large-scale structure in the universe including nonzero spatial curvature and a cosmological constant. In particular, we

Contribution of non-linear structure to the kinetic Sunyaev-Zeldovich power spectrum

In the last two decades, a satisfactory standard cosmological model has been established. On the other side, a wealth of new precise data from various astronomical observations is becoming available,

Perturbatively constructed cosmological model with periodically distributed dust inhomogeneities

We constructed a simple cosmological model which approximates the Einstein-de Sitter background with periodically distributed dust inhomogeneities. By taking the metric as a power series up to the
