| Description | M87 is a giant elliptical galaxy located at the centre of the Virgo Cluster. Known to host an extremely massive black hole, it is an active galaxy showing no signs of quasar-like activity. The very nature of its infrared emission is, at present, not completely unveiled. The spectral energy distribution longward of 10 microns is dominated by the radio jet, known since more than 50 years to be powered by synchrotron emission. Whether a fraction of the infrared radiation has a different origin, such as thermal emission from a dusty torus, or from a diffuse dust component, is not clear yet. We propose to perform deep observations of a field centered on M87 with PACS, at both 70 and 100 micron, at slow speed. In this way we will achieve the best possible spatial resolution, and the jet will be imaged at a very high S/N. Furthermore, we will be able to detect emission from the diffuse dust, if any, down to a few thousands solar masses. |

| 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. |
