It is now a known fact that if we happen to be living in the middle of a large underdense region, then we will observe an ``apparent acceleration'', even when any form of dark energy is absent. In this paper, we present a ``Minimal Void'' scenario, i.e. a ``void'' with minimal underdensity contrast (of about -0.4) and radius (~ 200−250 Mpc/h) that can, not only explain the supernovae data, but also be consistent with the 3-yr WMAP data. We also discuss consistency of our model with various… 

Constraints on large-scale inhomogeneities from WMAP5 and SDSS: confrontation with recent observations

Measurements of the Type Ia supernovae Hubble diagram which suggest that the Universe is accelerating due to the effect of dark energy may be biased because we are located in a 200–300 Mpc underdense

Reconciling the local void with the CMB

In the standard cosmological model, the dimming of distant Type Ia supernovae is explained by invoking the existence of repulsive ''dark energy'' which is causing the Hubble expansion to accelerate.

Testing the void against cosmological data: fitting CMB, BAO, SN and H0

In this paper, instead of invoking Dark Energy, we try and fit various cosmological observations with a large Gpc scale under-dense region (Void) which is modeled by a Lema?tre-Tolman-Bondi metric

Precision cosmology defeats void models for acceleration

The suggestion that we occupy a privileged position near the center of a large, nonlinear, and nearly spherical void has recently attracted much attention as an alternative to dark energy. Putting

Observational constraints on the ΛLTB model

We directly compare the concordance ΛCDM model to the inhomogeneous matter-only alternative represented by LTB void models. To achieve a ``democratic'' confrontation we explore ΛLTB models with

Observational constraints on the ?LTB model

We directly compare the concordance ?CDM model to the inhomogeneous matter-only alternative represented by LTB void models. To achieve a ``democratic'' confrontation we explore ?LTB models with

Distinguishing between void models and dark energy with cosmic parallax and redshift drift

Two recently proposed techniques, involving the measurement of the cosmic parallax and redshift drift, provide novel ways of directly probing (over a time span of several years) the background metric

Supernovae observations in a 'meatball' universe with a local void

We study the impact of cosmic inhomogeneities on the interpretation of observations. We build an inhomogeneous universe model without dark energy that can confront supernova data and yet is

A (giant) void is not mandatory to explain away dark energy with a Lemaître-Tolman model

Context. Lemaitre-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 mandatory to

Virialisation-induced curvature as a physical explanation for dark energy

The geometry of the dark energy and cold dark matter dominated cosmological model (LambdaCDM) is commonly assumed to be given by a Friedmann-Lemaitre-Robertson-Walker (FLRW) metric, i.e. it assumes
