Description Dust grains ejected into the hot interstellar gas in group-centered
elliptical (E) galaxies are destroyed by ion-grain collisions, but
during their short lifetime (10 Myrs) the grains emit sufficiently in
the far infrared (FIR) to be easily observable. Remarkably, against
this background emission, observations with Spitzer discovered many E
galaxies with much stronger and spatially extended FIR emission from
colder grains 5-10 kpc distant from the galaxy cores. Extended excess
cold dust emission is interpreted as evidence of recent
feedback-generated AGN energy outbursts in these galaxies, visible
only in the FIR, from buoyant gaseous outflows from the galaxy cores.
With Spitzer a quasi-radial plume of AGN-heated gas is resolved in
only one galaxy, but marginally resolved in others. We request
Herschel observations of a small sample of these E galaxies to confirm
the existence of excess, spatially extended dust and to possibly
spatially resolve more quasi-radial buoyant dusty gaseous plumes.
Based on a detailed analysis of Spitzer data, our sample for Herschel
is chosen to maximize the likelihood of discovering new FIR evidence
of post-feedback events from massive galaxy-centered black holes.

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.
