The research led by Dr. Daichi Kashino, a Project Assistant Professor (NAOJ Fellow) at the Division of Science, during his affiliation at Nagoya University, has been selected as one of the Top 10 Breakthroughs for 2023 by Physics World. Conducted under the international collaborative project named EIGER, this study used observations of distant galaxies with the James Webb Space Telescope (JWST) and successfully discovered “smoking gun” evidence of early galaxies transforming the universe about one billion years after the Big Bang through the process known as “cosmic reionization.” Dr. Kashino, who transferred to NAOJ in July 2023, is currently conducting more detailed analysis to better understand the role of early galaxies in cosmic reionization, incorporating newly obtained data from JWST.
