Abstract
Starting from a sample of type-2 AGN, the effect of the large-scale environmental density (LSED, parametrized by the surface density) on the mass of central black holes (MBH) and SFR in AGN is studied. We find there is not apparent dependence between the environment and these variables. The invariance LSED-MBH suggests that there are not traces in the Local Universe of the possible assembling (build-up) of central black holes via galaxy merging, or that the mass growth of the black holes obeys to other different mechanisms not related with the environment that surrounds those AGN host galaxies. On the other hand, the invariance LSED-SFR is consistent with previous studies. A strong correlation between black hole mass in AGN and the SDSS concentration indexes is finally reported.
