Activity Phenomena in Galaxies: a 3D Perspective from the Nucleus to the Outskirts

Description

This project has two lines of fundamental development. First, the application of 3D techniques, in particular of integral field spectroscopy, to the study of extended objects (nuclear activity in galaxies, star formation regions, etc), as well as the participation in the development of new instruments and data analysis procedures related to 3D techniques. In particular, we participate in the development of HARMONI, the first-light high-spatial resolution integral field spectrograph for the ESO Extremely Large Telescope (ELT). Second, the scientific exploitation of the GTC observations of galaxies with active nuclei (AGN) obtained with the infrared instruments CanariCam and EMIR and with ALMA in the sub-mm regime. The data is being used to characterize the dusty torus that obscures local AGN and to study quasar winds in luminous obscured AGN (AGN feedback). Moreover, this project is devoted to get observing time with the JWST as part of the GATOS consortium (Galactic Activity, Torus and Outflow Survey), as well as to exploit on-going ALMA observations of nearby AGN.

  • Investigating the sensitivity of observed spectral energy distributions to clumpy torus properties in Seyfert galaxies

    We present nuclear spectral energy distributions (SEDs) from 1 to 18 μm of a small sample of nearby, nearly face-on and undisturbed Seyfert galaxies without prominent nuclear dust lanes. These nuclear SEDs probe the central ˜35 pc of the galaxies, on average, and include photometric and spectroscopic infrared (IR) data. We use these SEDs, the
