Subaru Reveals "Frame Structures" of Galaxies at 11 billion Years Ago
A team of Japanese astronomers from the National Astronomical Observatory of Japan, Tokyo University, and Kyoto University in Japan obtained deep and high-resolution images of galaxies from 11 billion years ago using the adaptive optics (AO) system and the infrared camera and spectrograph (IRCS) on the Subaru Telescope. Thanks to the removal of atmospheric blur by the AO system, high spatial resolution imaging was achieved in the near-infrared and the profiles of the distant galaxies were revealed. The images of the distant galaxies show almost all of the galaxies have a light profile similar to the disk galaxies in the local universe.
