The Central PARSEC of Galaxies using High Spatial Resolution Techniques

Start year
2003
Description

The project PARSEC / high-angular-resolution-instrumentation is an investigation of the centre of the nearest galaxies accros the entire electromagnetic spectrum at spatial resolutions of a few parsecs. Thses resolutions are achievable today with  8-10m class telescopes  and state of the art observational techniques such as extreme Adaptive Optics (AO) and long-base-line Interferometry in which the project team is heaviliy involved in their development. The objectives of this project are twofold:

  1. Foster the development and application of high spatial resolution techniques for astronomy at the Spanish and GTC community at large. Those include adaptive optics, laser-guide star, speckle and optical interferometry. To that aim, this team is constructing the first adaptive optics instrument for GTC: FRIDA http://research.iac.es/proyecto/frida,  involved in the development of the Adaptive Optics  system GTCAO for GTC, and participate in the definition of second generation Adaptive Optics Systems for VLT.
  2. Pursue studies of centers of galaxies, and their energetic manifestations, with the highest possible spatial resolution possible today. Two research lines are studied:

2.1 Project PARSEC (Central PARSEC of galaxies): Multiwavelength investigation of the central PARSEC of across the entire electromagnetic spectrum http://research.iac.es/project/parsec

2.2 Project PAIS (Particle Accelerators In Space): Multiwavelength study of particles acceleration in jets and hot spots in radio galaxies http://research.iac.es/project/jets-and-hotspots-in-radiogalaxies/main/…

  • Tracing the Evolution of Dust Obscured Star Formation and Accretion Back to the Reionisation Epoch with SPICA

    Our current knowledge of star formation and accretion luminosity at high redshift (z > 3-4), as well as the possible connections between them, relies mostly on observations in the rest-frame ultraviolet, which are strongly affected by dust obscuration. Due to the lack of sensitivity of past and current infrared instrumentation, so far it has not

    Low-luminosity Active Galactic Nuclei (LLAGNs) are characterized for low-radiative efficiency, much less than one percent of their Eddington limit. Nevertheless, their main energy release may be mechanical, opposite to powerful AGN classes like Seyfert and Quasars. This work reports on the jet-driven mechanical energy and the corresponding mass

The 11 kpc (˜70 arcsec) diameter star-forming ring of the galaxy appears resolved up to 250 μm. We extracted IR (1.6-500 μm) nuclear fluxes
