The PARSEC project is a multi-wavelength study, at subarcsec scales, of the nuclear region of the brightest galaxies in the near Universe. We are using the highest available spatial resolution at the different spectral ranges, spanning the X-ray to radio range.
Most of the galaxies studied are active galactic nuclei (AGN). We are interested in the origin and distribution of dust and gas in the central parsecs of active and normal galaxies, these components being considered as pre-conditions for the onset of activity. The spectral energy distribution of the central few parsecs is investigated in relation to the level of nuclear activity. The nature and shape of the ionization spectrum against the activity level are studied via the analysis of the high ionization coronal lines.
