We detected a spatial anisotropy in the distribution of the nearby hard X-ray emitting AGNs and showed that it well correlates with known nearby anisotropies of the matter density distribution. Using the AGN sample from the INTEGRAL all sky survey we for the first time directly showed that the density fluctuations of the matter in the local Universe linearly translates to the density fluctuations of the accreting supermassive black holes (SMBHs) and measured their bias factor at zero redshift. The last was measured to be around unity which implies that the SMBH activity is independent from the density of galaxies.
