| Description |
This proposal is to obtain PACS spectroscopy of 10 bright Seyfert nuclei to observe the 6 ionic fine-structure lines, four high-J CO lines and three OH doublets. The selected targets include four AGN1s (two Seyfert 1s and two HBLR-Seyfert 2s), three AGN2s and three lower activity objects.These objects have been chosen because they are the brightest at 60-100 micron, their luminosity has been separated between AGN and Starburst components through mid-IR spectroscopy. The immediate goals are to obtain a large set of FIR tracers to be able to classify and model the various levels of non-thermal and starburst activity in local Seyferts, using both atomic (Herschel and Spitzer) and molecular (Herschel and H2 from Spitzer) transitions. The mid-to far-IR classification of activity in galaxies will be essential in the close future tointerpret the spectroscopic surveys at long wavelength that will be performed by Herschel, ALMA and SPICA.The range spectroscopy with PACS has been optimized to allow detectionof 4 CO lines, 3 OH doublets and 6 fine structure lines in a total time of 14.0 hours. |
