Model-independent test of the cosmic anisotropy with inverse distance ladder

Abstract If the Universe is endowed with cosmic anisotropy, it will have a preferred direction of expansion. By reconstructing the expansion history using a Gaussian process (GP), researchers can probe the cosmic anisotropy model-independently. In this paper, for the luminosity distance $$d_L(z)$$ d...
