Calls for Proposals

The University of California Observatories (UCO) is a multi-campus research unit. We operate the Lick Observatory, the technical labs at UC Santa Cruz and UCLA, and we are a managing partner of the Keck Observatory in Hawaii. We are the center for the UC participation in the Thirty-Meter Telescope (TMT) project.

    Face recognition for galaxies: Artificial intelligence brings new tools to astronomy

    April 23, 2018

    In a new study, accepted for publication in Astrophysical Journal and available online, researchers used computer simulations of galaxy formation to train a deep learning algorithm, which then proved surprisingly good at analyzing images of galaxies from the Hubble Space Telescope.

    Amateur astronomer captures rare first light from massive exploding star

    February 21, 2018

    Thanks to lucky snapshots taken by an amateur astronomer in Argentina, scientists have obtained their first view of the initial burst of light from the explosion of a massive star. (...)  "Professional astronomers have long been searching for such an event," said UC Berkeley astronomer Alex Filippenko, who followed up the discovery with observations at the Lick and Keck observatories that proved critical to a detailed analysis of explosion, called SN 2016gkg.


    Supermassive black holes control star formation in large galaxies.

    January 1, 2018

    Astronomers find close correlation between the mass of a galaxy's central black hole and its star formation history. Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves.
