PARSEC project

The central PARSEC of galaxies across the electromagnetic spectrum

IAC

PARSEC project is a multi-wavelength study at PARSEC scales of the nuclear region of the brightest galaxies in the near Universe. We are using the highest available spatial resolution accross the entire eletromagnetic spectrum from high energies to the cm waves.

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

PARSEC keeps a narrow collaboartion with the Computational Astrophysics group, CAST, from the Munchen Sternwarte to work on numerical and magnetic-hydrodynamic simulations of PARSEC data results.
