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 brightness of SN Ia through the empirical standardization would not evolve with look-back time. Recent studies have shown, however, that the standardized brightness of SN Ia is correlated with host morphology, host mass, and local star formation rate (SFR), suggesting a possible correlation with stellar… Expand
Supernovae and their host galaxies – VII. The diversity of Type Ia supernova progenitors
We present an analysis of the light curve (LC) decline rates (Δm15) of 407 normal and peculiar supernovae (SNe) Ia and global parameters of their host galaxies. As previously known, there is aExpand
Type Ia supernovae in the star formation deserts of spiral host galaxies
Using a sample of nearby spiral galaxies hosting 185 supernovae (SNe) Ia, we perform a comparative analysis of the locations and light curve decline rates $(\Delta m_{15})$ of normal and peculiar SNeExpand
Improving bayesian posterior correlation analysis on type Ia supernova luminosity evolution
Much of the cosmological utility thus far extracted from Type Ia supernovae (SNe Ia) relies on the assumption that SN~Ia peak luminosities do not evolve significantly with the age (local or global)Expand
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.Expand

The effort for understanding the matter and energy content of the Universe and its evolution relies on different probes, such as cosmic background radiation, cluster lensing, supernovae. Yet, we areExpand
Supernova Magnitude Evolution and PAge Approximation
The evidence of environmental dependence of Type Ia supernova luminosity has inspired recent discussion about whether the late-universe cosmic acceleration is still supported by supernova data. WeExpand
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 parametersExpand
Is there any measurable redshift dependence on the SN Ia absolute magnitude?
We test the cosmological implications of a varying absolute magnitude of Type Ia supernovae using the Pantheon compilation, by reconstructing different phenomenological approaches that could justifyExpand
Time Variance of Recession Velocities: a Potential Resolution to the ‘Crisis in Cosmology’ and a Possible Explanation for the Accelerating Universe Along with a Possible Direct Evidence for Inflation and Reheating
The larger than expected discrepancy between values of the Hubble-Lemaitre constant, among those measured by various seemingly independent methods, has been called as a ‘crisis’ in Cosmology. ByExpand
Re-evaluation of Ωk of the normalised Friedmann-Lemaître-Robertson-Walker model: Implications for Hubble constant determinations
Abstract The description of spacetime is an fundamental problem of cosmology. We explain why the current assignments of spacetime geometries for Ω k of the Friedmann-Lemaitre-Robertson-Walker (FLRW)Expand
