Galaxy Collisions Found to Activate Supermassive Black Holes, Euclid Data Shows
Astronomers using ESA’s Euclid telescope and AI analysis have found that merging galaxies are significantly more likely to host active supermassive black holes. The gravitational chaos of a collision drives gas toward the galactic core, igniting AGN activity. This discovery strengthens the link between galaxy interactions and the energetic processes that shape galactic evolution.
