Sept 14, 2011 - "The Next Generation Virgo Cluster Survey" - Nick Ball, Assistant Research Officer, HIA

The Virgo cluster of galaxies is the nearest large cluster of galaxies to us. In terms of the environment of the local universe, if the Milky Way galaxy is in the 'suburbs', Virgo is the nearest 'city'. And, like a city, things go on there that do not happen in other places, from which one may learn interesting things. The Next Generation Virgo Cluster Survey (NGVS) is a revolutionary new optical survey, probing 100 square degrees of this part of the sky much more deeply than has been done before. It will provide transformative progress towards answering many interesting questions, such as how many galaxies there are in the cluster, how faint they go, what their properties are over the huge range of sizes that they display, how they are affected by being in a cluster environment, what effect do the supermassive black holes at their centres have, and so on. In turn, these will enable us to better understand how galaxies and the universe came to be as they are today. Because the survey is deep, wide-field, high resolution, and in several bands, it also provides some spectacular new colour pictures of galaxies in Virgo, many of which are no doubt old friends to observers in the group, but are revealed in a new light by the NGVS.
