Description |
We propose to obtain PACS and SPIRE imaging observations of a sample of nearby (d<60Mpc) Seyfert galaxies. The main goal of this proposal is to understand the processes heating the dust in nearby Seyfert galaxies, including dust heated by the AGN, by on-going star formation activity, and by the general ISM radiation field. The galaxies are part of our own survey of local AGN to be observed with the mid-infrared CanariCam instrument on the 10.4-m Gran Telescopio Canarias. The sample contains 31 Seyferts of different types (1, 1.5, 1.8, 1.9, 2) and covers a large range in AGN luminosities. In this proposal we only apply for observing time for those galaxies not observed previously with PACS and SPIRE. The unprecedented angular resolution and sensitivity of the proposed PACS and SPIRE imaging observations will be used to: (1) map and quantify the on-going star formation activity across the host galaxies of local AGN, (2) obtain spatially-resolved and integrated accurate estimates of the dust temperature and content of the host galaxies, and (3) put tighter constraints on the properties of the clumpy torus by fitting their nuclear IR spectral energy distributions. |
