Astronomers Discover Massive Cosmic Vine Galaxy Structure
An international team of astronomers has recently made a groundbreaking discovery in the universe. They have identified an extensive galaxy structure named “Cosmic Vine,” which measures approximately 13 million light-years in length and contains at least 20 massive galaxies. This structure was observed at a redshift of 3.44, indicating its appearance when the universe was just a 2.5 billion-year-old infant.
The significance of uncovering Cosmic Vine lies in the new perspectives it offers on the formation and evolution of massive galaxies. The structure is believed to serve as the precursor to a galaxy cluster, providing insights into the formation of such clusters and the emergence of massive galaxies within them.
The discovery also implies that massive quiescent galaxies can form within expanding large-scale structures, contrary to prior models suggesting their exclusive formation in the cores of mature galaxy clusters. Researchers propose that two of the most massive galaxies within the Cosmic Vine structure, Galaxy A and Galaxy E, were likely subdued by substantial energy releases from a supermassive black hole before eventually succumbing to the Vine’s core.
To gain a deeper understanding of the formation of these giants, further examination of quiescent cluster galaxies at high redshifts is imperative. The recently launched Euclid Space Telescope, designed to investigate the structure and history of large-scale structures in the universe, holds promise in advancing this research.
The research findings have been published in a preprint journal and can be accessed here. This discovery opens up new possibilities for understanding the formation and evolution of galaxies and large-scale structures in the universe.
