The growth of cosmic structures is investigated through the analyses of f(z) and σ8(z) cosmic
observables data, using non-parametric Gaussian Process reconstructions combined with
MCMC statistical analyses. The standard ...

Spectral line lists constitute the foundation for spectral synthesis calculations
and the determination of chemical abundances, including those
derived from large spectroscopic surveys such as SDSS–APOGEE. This
project ...

trophysics, as effective temperature (Teff ), surface gravity (log g), and metallicity (rFe{Hs)
are the primary observables that describe stellar structure and evolution. Traditionally,
these quantities are derived from ...
