Description We propose SPIRE FTS spectra to determine the source of heating
of the cool/warm (100-300 K) gas in the Brightest Cluster Galaxy
NGC-1275, the brightest of all cluster cool-core galaxies. The
heating mechanism in BCGs is unknown and crucial to understanding
analogous negative feedback processes in star-forming galaxies
at high redshift. Our current mm-CO, PACS, nearIR and optical data
on this cluster indicate that the SPIRE measurements will detect
many CO lines and possibly H2O+ and OH+ lines that will
determine the temperature, and density of the most important
component of this warm gas. The ratios of the CO lines, and
the presence or absence of the ionized lines, and the
dependence of these lines with distance from the central AGN should
allow us to choose between the several possible heating
and excitation mechanisms: soft X-rays, cosmic ray ionization,
and C- and J- shocks from AGN induced turbulence.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
