This galaxy protocluster is situated at a staggering distance of 13.14 billion light-years from Earth.
ALMA targeted detecting radio emissions from dust within these faraway galaxies. After thorough analysis, they identified dust emissions in three of the four galaxies.
These powerful cosmic explosions eject significant amounts of material that subsequently serve as the building blocks for forming next-generations of stars. "Emission from cosmic dust was not detected in member galaxies of the protocluster outside the core region. The results indicate that many galaxies are clustered in a small region, and galaxy growth is accelerated, suggesting that environmental effects existed only ~700 million years after the Big Bang," said Luis Colina.
Scientists conducted computational simulations to explore the evolution of the four galaxies in the cluster's center area.

James Webb Space Telescope and ALMA capture the core of the most distant galaxy protoclusterThe study of how individual stars are born and die in galaxies, how new stars are born from remnants of old stars, and how galaxies themselves grow are important themes in astronomy, as they provide insight into our roots in the universe. Galaxy clusters, one of the largest structures in the universe, are the assembly of more than 100 galaxies which are bound together through mutual gravitational force.

Tag team of the James Webb Space Telescope and ALMA captures the core of the most distant galaxy protoclusterAn international research team has used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. The team has successfully captured the 'core region' of the galaxy protocluster, which corresponds to a metropolitan area with a particularly high number density of galaxies. The team has revealed that many galaxies are concentrated in a small area and that the growth of galaxies is accelerated. Furthermore, the team used simulations to predict the future of the metropolitan area and found that the region will merge into one larger galaxy within tens of millions of years. These results are expected to provide important clues regarding the birth and growth of galaxies.
