An effective description of Laniakea: impact on cosmology and the local determination of the Hubble constant

L. Giani, C. Howlett, K. Said +2

We propose an effective model to describe the bias induced on cosmological observables by Laniakea, the gravitational supercluster hosting the Milky Way, which was defined using pe…
