Constructing A 3D Map Of The Large-Scale Structure Of The Universe


An international team led by astronomers from Kyoto University, the University of Tokyo and the University of Oxford has released its first version of a 3D map of the Universe from its FastSound project, which is surveying galaxies in the Universe over nine billion light years away. Using the Subaru Telescope’s new Fiber Multi-Object Spectrograph, the team’s 3D map includes 1,100 galaxies and shows the large-scale structure of the Universe nine billion years ago.

The FastSound project, one of Subaru Telescope’s Strategic Programs, began its observations in March 2012 and will continue them into the spring of 2014. Although surveys with 3D maps of the Universe have been conducted on the nearby Universe (e.g., the Sloan Digital Sky Survey with coverage up to five billion light years away), the FastSound project distinguishes itself by developing a 3D map of the far-distant Universe, covering the largest volume of the Universe farther than ten billion light years away (in comoving distance).
