If the FRW metric is a good approximation on large scales, then the distance and the expansion rate, as well different notions of distance, satisfy certain consistency conditions. We fit the JLA SNIa distance data to determine the expected amplitude of the violation of these conditions if accelerated expansion is due to backreaction. Adding cosmic clock and BAO expansion rate data, we also model-independently determine the current observational limits on such violation. We find that the… 
Falsifying ΛCDM : Model-independent tests of the concordance model with eBOSS DR14Q and Pantheon
We combine model-independent reconstructions of the expansion history from the latest Pantheon supernovae distance modulus compilation and measurements from baryon acoustic oscillation to test some
Dynamical spatial curvature as a fit to Type Ia supernovae
Few statements in cosmology can be made without assuming a cosmological model within which to interpret data. Statements about cosmic acceleration are no exception to this rule, and the inferred
Solving the curvature and Hubble parameter inconsistencies through structure formation-induced curvature
Recently it has been noted by Di Valentino, Melchiorri and Silk (2019) that the enhanced lensing signal relative to that expected in the spatially flat $\Lambda$CDM model poses a possible crisis for
Kinematic constraints on spatial curvature from supernovae Ia and cosmic chronometers
An approach to estimate the spatial curvature $\Omega_k$ from data independently of dynamical models is suggested, through kinematic parameterizations of the comoving distance ($D_{C}(z)$) with third
Direct test of the FLRW metric from strongly lensed gravitational wave observations
This study demonstrates that the third-generation ground based GW detectors, like the Einstein Telescope and space-based detectors, are promising concerning determination of the curvature parameter or possible detection of deviation from the FLRW metric.
Model-Independent Determination of H_{0} and Ω_{K0} from Strong Lensing and Type Ia Supernovae.
The first determination of the Hubble constant H_{0} is presented from strong lensing time delay data and type Ia supernova luminosity distances and the spatial curvature model is determined independently.
Null tests of the standard model using the linear model formalism
We test both the FLRW geometry and $\Lambda$CDM cosmology in a model independent way by reconstructing the Hubble function $H(z)$, the comoving distance $D(z)$ and the growth of structure
Extended gravity cosmography
Cosmography can be considered as a sort of a model-independent approach to tackle the dark energy/modified gravity problem. In this review, the success and the shortcomings of the [Formula: see
Evaluating backreaction with the ellipsoidal collapse model
We evaluate the effect of structure formation on the average expansion rate with a statistical treatment where density peaks and troughs are modelled as homogeneous ellipsoids. This extends earlier
Analytical solutions for two inhomogeneous cosmological models with energy flow and dynamical curvature
Recently we have introduced a nonrelativistic cosmological model (NRCM) exhibiting a dynamical spatial curvature. For this model the present day cosmic acceleration is not attributed to a negative


Smoothing expansion rate data to reconstruct cosmological matter perturbations
The existing degeneracy between different dark energy and modified gravity cosmologies at the background level may be broken by analysing quantities at the perturbative level. In this work, we apply
Using H(z) data as a probe of the concordance model
Direct observations of the Hubble rate, from cosmic chronometers and the radial baryon acoustic oscillation scale, can outperform supernovae observations in understanding the expansion history,
Observational constraints on the acceleration of the Universe
We propose a new parametrization of the deceleration parameter to study its time-variation behavior. The advantage of parameterizing the deceleration parameter is that we do not need to assume any
Bayesian analysis and constraints on kinematic models from union SNIa
The kinematic expansion history of the universe is investigated by using the 307 supernovae type Ia from the Union Compilation set. Three simple model parameterizations for the deceleration parameter
A 6% measurement of the Hubble parameter at z∼0.45: direct evidence of the epoch of cosmic re-acceleration
Deriving the expansion history of the Universe is a major goal of modern cosmology. To date, the most accurate measurements have been obtained with Type Ia Supernovae (SNe) and Baryon Acoustic
Is cosmic acceleration proven by local cosmological probes
Context: The cosmological concordance model ($\Lambda$CDM) matches the cosmological observations exceedingly well. This model has become the standard cosmological model with the evidence for an
Evidence for a lower value for H0 from cosmic chronometers data
An intriguing discrepancy emerging in the concordance model of cosmology is the tension between the locally measured value of the Hubble rate, and the ‘global’ value inferred from the cosmic
Cosmography and constraints on the equation of state of the Universe in various parametrizations
We use cosmography to present constraints on the kinematics of the Universe, without postulating any underlying theoretical model. To this end, we use a Monte Carlo Markov Chain analysis to perform
Cosmography: Extracting the Hubble series from the supernova data
We perform a number of inter-related cosmographic fits to the legacy05 and gold06 supernova datasets. We pay particular attention to the influence of both statistical and systematic uncertainties,
