3D intergalactic map will reveal details about dark matter, black holes and stars

The first 3D map of hundreds of galaxies in the local universe is poised to increase our understanding of nearby galaxies and galactic clusters, showing how they form and change over time.

Covering three-quarters of the sky, the map should help scientists measure the distribution of gas and dark matter in the local universe, as well as gain a much-improved understanding of the processes involved in galaxy formation and evolution and the role black holes play in this galactic development.
