| Description | Dust grains ejected into the hot interstellar gas in group-centeredelliptical (E) galaxies are destroyed by ion-grain collisions, butduring their short lifetime (10 Myrs) the grains emit sufficiently inthe far infrared (FIR) to be easily observable. Remarkably, againstthis background emission, observations with Spitzer discovered many Egalaxies with much stronger and spatially extended FIR emission fromcolder grains 5-10 kpc distant from the galaxy cores. Extended excesscold dust emission is interpreted as evidence of recentfeedback-generated AGN energy outbursts in these galaxies, visibleonly in the FIR, from buoyant gaseous outflows from the galaxy cores.With Spitzer a quasi-radial plume of AGN-heated gas is resolved inonly one galaxy, but marginally resolved in others. We requestHerschel observations of a small sample of these E galaxies to confirmthe existence of excess, spatially extended dust and to possiblyspatially resolve more quasi-radial buoyant dusty gaseous plumes.Based on a detailed analysis of Spitzer data, our sample for Herschelis chosen to maximize the likelihood of discovering new FIR evidenceof 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. |
