Supermassive black holes (SMBH) with mass greater than 1 million solar masses are found in the core of most massive galaxies in the local Universe. The relationship between the mass of the spheroidal component of the host galaxy and that of their central BH known as the BH-bulge mass relationship has been widely studied. We present a new phenomenological BH-bulge mass relationship with redshift evolution and compare it to the population of BHs produced by six large-scale cosmological simulations. We compare the growth of BHs with redshift in Illustris, Horizon-AGN, SIMBA, TNG100, TNG300, and EAGLE.
