Testing the cosmological principle in the radio frequencies

08.11.2019 11:30 – 12:30

The Cosmological Principle, i.e., the assumption of large-scale isotropy and homogeneity of the Universe, comprises one of the fundamental hypothesis of the standard model of Cosmology. It is thus crucial to test whether it holds true in light of observational data. A possible way to do it is to verify if the dipole seen in the CMB, ascribed to our relative motion through the sky, can also be detected in the large-scale structure through galaxy number counts. Radio continuum surveys provide a great opportunity for that as they can reach high redshifts $(0
