Resumen:
We use a combination of a cosmological N-body simulation of the concordance Lambda Cold Dark Matter (Lambda CDM) paradigm and a semi-analytic model of galaxy formation(Lagos, Cora & Padilla 2008), to study the spins of central super-massive black holes (SMBH), and the relations between the BH spin and mass, and the morphology and radio-loudness of host galaxies. In order to compute BH spins we use the alpha model (Shakura & Sunyaev 1973) and consider a warped disc treatment (King et al. 2005). The direction of the BH spin is inferred from the angular momentum of the source of the accreted material, which encodes information on the evolution of the surrounding large-scale structure.
