Astronomers from the University of Southampton and other institutions have found evidence that giant elliptical galaxies formed from collisions between disc galaxies 8 to 12 billion years ago. Using the ALMA radio telescope, they analyzed over 100 star-forming galaxies and discovered intense star formation within their cores, leading to the creation of spheroidal galaxies. This discovery, published in Nature, suggests that gas sinking towards the center of colliding galaxies ignites star formation, forming trillions of new stars. The findings will be combined with data from the James Webb and Euclid satellites to deepen understanding of early galaxy formation.
