摘要: The growth index of matter fluctuations is computed for ten distinct accelerating cosmological models and confronted by the latest growth-rate data via a two-step process. First, we implement joint statistical analysis in order to place constraints on free parameters all using solely background data. Second, observed rate clustering from various galaxy surveys test performance current at perturbation level while either marginalizing over ${\ensuremath{\sigma}}_{8}$ or having it as parameter. As result, find that level, i.e., after considering best-fit ${\ensuremath{\chi}}^{2}$ value Akaike information criterion, most are very good agreement with practically indistinguishable $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$. However, when also consider internal consistency comparing theoretically predicted values $({\ensuremath{\gamma}}_{0},{\ensuremath{\gamma}}_{1})$, $\ensuremath{\gamma}(z)$ its derivative today, ones, predictions three out dark energy mild tension ones marginalized over. When not only tension, but predict low ${\ensuremath{\sigma}}_{8}$. This could be attributed systematic problem emergence new physics redshifts, latter possibly being related well-known issue lack power small scales. Finally, utilizing mock based an large synoptic survey telescope-like show future parametrization, will possible resolve between fitted $({\ensuremath{\gamma}}_{0},{\ensuremath{\gamma}}_{1})$.
