dc.description.abstract | Using the gas mass fraction fgas measurements obtained on the basis
of X-ray data for two samples of hot and dynamically relaxed galaxy clusters:
42 clusters with redshifts in the range of 0:05 < z < 1:1 collected and
analysed by Allen et al. (2008) and 35 clusters at redshifts 0:15 < z < 0:30
selected and analysed by Landry et al. (2013), we obtained constraints
on main cosmological parameters in two popular cases: wCDM model in
which dark energy equation of state is constant in time and the model in
which dark energy equation of state evolves with redshift according to the
Chevalier–Polarski–Linder (CPL) parametrization. [...] This shows that galaxy clusters can be used as a
good tool in cosmology. Moreover, we investigate the recent (i.e. at low
redshift) expansion history of the Universe finding no evidence that the
cosmic acceleration is now slowing down. | pl_PL |
