Abstract

In this work, we have treated and analyzed data cubes of 8 nearby active galactic nuclei, in the optical and in the infrared. All data cube treatment and analysis were performed using a series of specific methodologies, many of which were developed in the last few years by the author\'s working group. The analysis of all data cubes was performed with four main objectives: analysis of the general phenomenology of the AGN environment, using PCA Tomography; analysis of the stellar populations, of the thermal emission from dust and of the featureless continuum in the vicinity of the AGN, with a spectral synthesis performed with the Starlight software; analysis of the stellar and gas kinematics around the central black hole and, in some cases, simulations with the purpose of determining the mass of the black hole; analysis of the excitation and ionization mechanisms of the gas or of the emission from molecular hydrogen.
