Description We propose PACS [CII], [OI] and [NII] spectra to determine the
source of heating for the cool (20-300 K) gas in an isolated,
quiescent gas filament in the Brightest Cluster Galaxy (BCG)
NGC-1275, the brightest of all cluster cool-core galaxies. The
heating mechanism of this cool gas in BCGs is not well understood,
It is also crucial to understanding analogous negative feedback
processes in star-forming galaxies at high redshift. In combination
with our SPIRE spectroscopy, and other deep multi-wavelength
measurements, the proposed observations will provide a unique
data set that will allow us to develop a consistent physical picture
of the processes that energize the filaments. NGC-1275 is the only
cool-core BCG where we can separate the quiescent filaments from
the nuclear region influenced by the AGN. This will allow us to
directly compare the heating of cool gas in these filaments with that
in the nuclear region.

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.
