Breakthrough in Understanding Formation of Giant Galaxies

Astronomers from the University of Southampton and international collaborators have made significant progress in understanding the formation of the universe's largest elliptical galaxies. Their study, published in Nature, suggests that these galaxies formed through intense star formation episodes triggered by collisions of disk galaxies and large flows of cold gas in the early universe. Using the ALMA radio telescope, researchers analyzed over 100 distant star-forming galaxies, providing evidence that spheroids form directly in the cores of these galaxies. This research aims to deepen our understanding of early galaxy formation and the universe's evolution.
