Evaluating backreaction with the peak model of structure formation
We evaluate the average expansion rate of a universe which contains a realistic evolving ensemble of non-linear structures. We use the peak model of structure formation to obtain the number density
Non-comoving baryons and cold dark matter in cosmic voids
We examine the fully relativistic evolution of cosmic voids constituted by baryons and cold dark matter (CDM), represented by two non-comoving dust sources in a $$\varLambda $$ΛCDM background. For
A SIMPLE GRAVITATIONAL LENS MODEL FOR COSMIC VOIDS
We present a simple gravitational lens model to illustrate the ease of using the embedded lensing theory when studying cosmic voids. It confirms the previously used repulsive lensing models for deep
Towards a Full Modelling of the iSW Effect
TLDR
This chapter explores the possible impact of individual structures on the CMB in the previous chapter and proves the existence and characteristics of the Dark Energy with this method.
Constructing realistic Szekeres models from initial and final data
The Szekeres family of inhomogeneous solutions, which are defined by six arbitrary metric functions, offers a wide range of possibilities for modelling cosmic structure. Here we present a model
Making sense of the bizarre behavior of horizons in the McVittie spacetime
The bizarre behavior of the apparent (black hole and cosmological) horizons of the McVittie spacetime is discussed using, as an analogy, the Schwarzschild-de Sitter-Kottler spacetime (which is a
Black holes in the Universe: Generalized Lemaitre-Tolman-Bondi solutions
We present newexact solutions which presumably describe black holes in the background of a spatially flat, pressureless dark-matter-or dark matter plus dark energy (DM + DE)- or quintom-dominated
Inhomogeneous cosmological models: exact solutions and their applications
Recently, inhomogeneous generalizations of the Friedmann?Lema?tre?Robertson?Walker (FLRW) cosmological models have gained interest in the astrophysical community and are more often employed to study
Dynamics of Void and its Shape in Redshift Space
We investigate the dynamics of a single spherical void embedded in a Friedmann- Lema^ tre universe, and analyze the void shape in the redshift space. We nd that the void in the redshift space appears
Cosmological expansion and local systems: exact solutions
We study the competition between cosmological expansion and local attraction for relativistic objects embedded in a generic Friedmann universe. The recently discovered “all or nothing” behaviour

Enlargement of a Void in the Expanding Universe
In the Einstein-de Sitter model, the spherically symmetric less-dense perturbation is in­ vestigated with an aim to discuss the observed void in distribution of galaxies. In the nonlinear regime, the
The structure and expansion law of a shock wave in an expanding universe
The structure and expansion law of a shock wave, generated by explosions of pregalactic objects or young galaxies in the early universe, is investigated with specific consideration of the expansion
Galaxy formation in an intergalactic medium dominated by explosions
The evolution of galaxies in an intergalactic medium dominated by explosions of star systems is considered analogously to star formation by nonlinearly interacting processes in the interstellar
Void in the Closed Universe
Motivated by the observation of a large void in the distribution of galaxies, the dynamics of a less-dense domain of matter, which we call a void, in the expanding universe was investigated by one of
