100 Ways to Die in the Universe: Falling Into a Cluster
Carnegie Institution for Science - The Huntington Library
The Hubble sequence of galaxies resembles a simple classification chart, yet underneath the neatly aligned shapes and colors lie complex and violent histories. Through radio, infrared, UV and optical astronomy, today we can deduce these histories - and the future. Nearby examples of every stage in the Hubble sequence provide living galactic fossils that reveal their 10 billion years of evolution. Dr. Alatalo will tour the Hubble sequence, exploring three avenues to galactic transitions: the quiet, slow fade; the violent merger; and the quietly violent evolution of a galaxy, likely due to a supermassive black hole in its center. By exploring how each piece of the puzzle fits with every other piece, we can understand the evolution of the Universe and fundamental questions of how we got here.
