| Abstract: |
Virgo is an Abell richness Class I cluster containing more than 2000 optically catalogued galaxies. At a distance of ∼17 Mpc, is the most nearby cluster of galaxies and one of the best studied at all wavelengths. The Herschel Virgo Cluster Survey is an approved Herschel Open Time Key Project that will map a considerable portion of Virgo in five bands (100, 160, 250, 350 and 500 μm) completing in this way the panchromatic view of its galaxies. Once the survey is completed, we will have scanned four 16-sq deg regions of the cluster eight times each, which will allow to reach the confusion limit at 250 μm. The analysis of the Science Demonstration Phase (SDP) field, that was observed in Nov. 2009, allowed us to achieve impressive results, that are reviewed in this talk, and which include the first observations of truncated dust discs due to the cluster environment, the first convincing far infrared (FIR) detection of dE galaxies in a cluster, the resolved dust surface density and temperature maps of galaxies and the confirmation of the non-thermal origin of the IR emission in M87. |
