Description
The standard model of cosmology is founded on the cosmological principle which
is the hypothesis of large-scale homogeneity and isotropy of the Universe.This hypothesis imposes that the rest frame of distant galaxies coincides with the rest frame of CMB. I will present some of the results we have obtained using the latest catalogues of radio galaxies and quasars which show that the cosmological principle might be violated [1,2]. I will then briefly discuss how the Rubin/LSST photometric catalog of galaxies, extending to redshifts beyond z >~ 2, could be used to check and possibly confirm the above mentioned results.
