Using HII galaxies and SDSS-DR13 clusters to address the Hubble constant and S8 tensions respectively
Abstract: I will present results related to the Hubble constant tension, by using HII galaxies as an alternative Hubble expansion tracer, and to the S8 tension by using the observed Cluster Mass Function, based on the recent SDSS-DR13 GalWCat19 sample, and a wide range of theoretical Halo Mass Function models.
