In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of? that …
We construct an updated and extended compilation of growth-rate data based on recent redshift-space distortion measurements. The data set consists of 34 data points and includes …
The phenomenological parametrizations of dark-energy (DE) equations of state can be very helpful, since they allow for the investigation of its cosmological behavior despite the fact …

We present independent determinations of cosmological parameters using the distance estimator based on the established correlation between the Balmer line luminosity, L (H β) …
In this work, we use an observational approach and dynamical system analysis to study the cosmological model recently proposed by Saridakis (2020), which is based on the …

We use H ii starburst galaxy apparent magnitude measurements to constrain cosmological parameters in six cosmological models. A joint analysis of H ii galaxy, quasar angular size …
The accelerated expansion of the Universe is one of the main discoveries of the past decades, indicating the presence of an unknown component: the dark energy. Evidence of …
The relationship between the integrated H β line luminosity and the velocity dispersion of the ionized gas of H ii galaxies and giant H ii regions represents an exciting standard candle …

We compare the constraints from two (2019 and 2021) compilations of H ii starburst galaxy (H iiG) data and test the model independence of quasar (QSO) angular size data using six …
