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/…

  • Variability of the blazar 4C 38.41 (B3 1633+382) from GHz frequencies to GeV energies

    Context. After years of modest optical activity, the quasar-type blazar 4C 38.41 (B3 1633+382) experienced a large outburst in 2011, which was detected throughout the entire electromagnetic spectrum, renewing interest in this source. Aims: We present the results of low-energy multifrequency monitoring by the GLAST-AGILE Support Program (GASP) of

    We present the first sub-arcsecond resolution two-dimensional stellar kinematics and X-ray observations of the prototypical starburst galaxy NGC 253 which define the position and nature of the galactic nucleus. These observations comprise some of the best probes of the central 300 pc of NGC 253, the nearest massive galaxy undergoing a powerful

  • Radio observations of extreme ULXs: revealing the most powerful ULX radio nebula ever or the jet of an intermediate-mass black hole?

    The most extreme ultraluminous X-ray sources (ULXs), with LX > 5 × 1040 erg s-1, are amongst the best candidates for hosting intermediate-mass black holes (IMBHs) in the haloes of galaxies. Jet radio emission is expected from a sub-Eddington accreting IMBH in the low/hard (radio bright) state. In a search for such IMBH jet radio emission, we have
