"Unprecedented Discovery: James Webb Space Telescope and ALMA Reveal Core of Distant Galaxy Protocluster"
The James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA) have captured the core region of the most distant galaxy protocluster, known as A2744z7p9OD. The research team detected ionized oxygen-ion light from four galaxies in the core region, confirming their membership in the protocluster. They also detected dust emissions from three of the four galaxies, indicating the presence of mature stars and accelerated galaxy growth. Galaxy formation simulations showed that the four galaxies in the core region merge and evolve into a larger galaxy within a few tens of millions of years. Further observations and analysis will be conducted to explore the growth mechanism of galaxies and our origins in the universe.
