Context. The cosmological concordance model (ΛCDM) is the current standard model in cosmology thanks to its ability to reproduce the observations. The first observational evidence for this model appeared roughly 20 years ago from the type-Ia supernovae (SNIa) Hubble diagram from two different groups. However, there has been some debate in the literature concerning the statistical treatment of SNIa, and their stature as proof of cosmic acceleration. Aims. In this paper we relax the standard… 
A non-parametric test of variability of Type Ia supernovae luminosity and CDDR
The first observational evidence for cosmic acceleration appeared from Type Ia supernovae (SNe Type Ia) Hubble diagram from two different groups. However, the empirical treatment of SNe Type Ia and
CMB Tensions with Low-Redshift H0 and S8 Measurements: Impact of a Redshift-Dependent Type-Ia Supernovae Intrinsic Luminosity
TLDR
The Dark Energy equation of state as a function of redshift is reconstructed, while the impact of type-Ia supernovae (SNIa) redshift-dependent astrophysical systematic effects on these tensions are studied.
Do supernovae indicate an accelerating universe?
In the late 1990’s, observations of two directionally-skewed samples of, in total, 93 Type Ia supernovae were analysed in the framework of the Friedmann-Lemâıtre-Robertson-Walker (FLRW) cosmology.
Model independent expansion history from supernovae: Cosmology versus systematics
We examine the Pantheon supernovae distance data compilation in a model independent analysis to test the validity of cosmic history reconstructions beyond the concordance ΛCDM cosmology. Strong
Early-type Host Galaxies of Type Ia Supernovae. II. Evidence for Luminosity Evolution in Supernova Cosmology
The most direct and strongest evidence for the presence of dark energy is provided by the measurement of galaxy distances using SNe Ia. This result is based on the assumption that the corrected
Quantifying the evidence for the current speed-up of the Universe with low and intermediate-redshift data. A more model-independent approach
We reconstruct in this paper the deceleration and jerk parameters as functions of the cosmological redshift from data on cosmic chronometers (CCH), baryon acoustic oscillations (BAOs), and the
On model independent cosmic determinations of $H_0$
TLDR
In a direct comparison of GP with the CPL model, the simplest model of dynamical dark energy, it is seen that correlations are suppressed by GP relative to CPL, therefore, GP cannot be model independent.
Hubble tension or a transition of the Cepheid SnIa calibrator parameters?
We re-analyze the Cepheid data used to infer the value of the Hubble constant H0 by calibrating Type Ia supernovae. We do not enforce a universal value of the empirical Cepheid calibration parameters

Cosmological Constraints from Low-Redshift Data
In this paper we summarise the constraints that low-redshift data—such as supernovae Ia (SN Ia), baryon acoustic oscillations (BAO) and cosmic chronometers (CC)—are able to set on the concordance
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
Cosmological Parameter Extraction and Biases from Type Ia Supernova Magnitude Evolution
We study different one-parametric models of type Ia Supernova magnitude evolution on cosmic time scales. Constraints on cosmological and Supernova evolution parameters are obtained by combined fits
OBSERVATIONAL EVIDENCE FROM SUPERNOVAE FOR AN ACCELERATING UNIVERSE AND A COSMOLOGICAL CONSTANT
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods that
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
Apparent cosmic acceleration from Type Ia supernovae
Parameters that quantify the acceleration of cosmic expansion are conventionally determined within the standard Friedmann-Lemaitre-Robertson-Walker (FLRW) model, which fixes spatial curvature to be

Model- and calibration-independent test of cosmic acceleration
We present a calibration-independent test of the accelerated expansion of the universe using supernova type Ia data. The test is also model-independent in the sense that no assumptions about the
Is the expansion of the universe accelerating? All signs point to yes
The accelerating expansion of the universe is one of the most profound discoveries in modern cosmology, pointing to a universe in which 70% of the mass-energy density has an unknown form spread
