Astronomers Unveil Growing Black Holes in Colliding Galaxies

An international team of researchers, including Claudio Ricci, professor of the Nucleo de Astronomia, performed the largest survey of the cores of nearby galaxies in near-infrared light, using high-resolution images taken by NASA’s Hubble Space Telescope and the W. M. Keck Observatory in Hawaii. The Hubble observations represent over 20 years’ worth of snapshots from …
