A team of astronomers have used the combination of the Subaru and Gemini telescopes on Maunakea to get a more detailed view than ever before, of a distant cluster of galaxies. Using a technique known as photometric redshift to estimate distances to astronomical objects, the astronomers created a 3-D map of the galaxy cluster CL1604, which is located 7.3 billion light-years from Earth. These new results are helping us understand how galaxies form and evolve, and show how powerful the combination of telescopes on Maunakea can be.
