PARSEC project

The central parsec of galaxies across the electromagnetic spectrum



The PARSEC project is a multi-wavelength study at subarcsec scale of the nuclear region of the nearest galaxies. We are using the highest available spatial resolution accross the entire eletromagnetic spectrum from the high energies to the radio-cm range to produce a consistent view of the same physical region in galaxies centre accros the spectrum.

The galaxies under study cover an extensive range of nuclear activity level, from quiesent state to low luminosity active nuclei to the highest level in the Seyfert and Qso phase. The PARSEC project focuses on the origin, morphology and dynamics of dust and gas in the centre of active and normal galaxies, as these being the pre-conditions for the onset of activity. The spectral energy distribution of the central few parsecs is investigated as a function of the nuclear activity level and accretion disc efficency. The nature and shape of the ionization spectrum are traced via the analysis of the high ionization coronal lines.
