Using the Subaru Telescope and Gemini-North Telescope, a team of astronomers has revealed that the supercluster CL1604, a distant supercluster located about 7.3 billion light-years away, is a large-scale 3-D structure extending over about 160 million light-years in the north-south direction. This is more than two times more extended than previously known. Until now, astronomers saw merely the “tip of the iceberg” of this supercluster. The wide-field capability of the Subaru Telescope enabled the team to survey the whole of the supercluster and the Gemini-North Telescope played a critical role in confirming the structures. This is the outcome of the synergy of the telescopes of the Maunakea observatories.
