| Description |
We propose to obtain PACS and SPIRE imaging observations of a sampleof nearby (d<60Mpc) Seyfert galaxies. The main goal of this proposal is tounderstand 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 CanariCaminstrument on the 10.4-m Gran Telescopio Canarias. The sample contains31 Seyferts of different types (1, 1.5, 1.8, 1.9, 2) and covers a large range in AGN luminosities. In this proposal we onlyapply for observing time for those galaxies not observed previouslywith PACS and SPIRE. The unprecedented angular resolution andsensitivity of the proposed PACS and SPIRE imaging observations willbe used to: (1) map and quantify the on-going star formation activityacross 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. |
