In this work,we explore the potentiality of future gravitational wave(GW) and Type la supernovae(SNe la) measurements to detect cosmic opacity by comparing the opacity-free luminosity distance(LD) of...
We discuss,using a recently proposed parametrization for the growth index of linear matter perturbations,the observational constraints on the wCDM model and the Dvali-Gabadadze-Porrati (DGP) model wi...
