Astronomers using ALMA and the Very Large Telescope observed two galaxies engaged in a 11-billion-year-old cosmic collision. One galaxy, harboring a quasar, is emitting radiation directly into its companion, disrupting star formation. This high-velocity interaction, visible due to ALMA's high resolution, reveals a quasar's destructive impact on a neighboring galaxy's gas and dust, hindering its stellar evolution. The findings, published in Nature, provide insight into galactic mergers and the role of quasars in shaping galactic structures.
