Cosmic radiation from supernova altered virus evolution in Africa, study proposes
A new study led by recent undergraduate student Caitlyn Nojiri and co-authored by astronomy and astrophysics professor Enrico Ramirez-Ruiz and postdoctoral fellow Noémie Globus examined iron isotopes to identify a 2.5 million-year-old supernova. The researchers connected this stellar explosion to a surge of radiation that pummeled Earth around the same time, and they assert that…

Hubble Telescope images combined into giant mosaic of neighboring Andromeda Galaxy
Astronomers are celebrating the completion of a 2.5-billion-pixel panoramic picture of the entire Andromeda Galaxy. The team includes several UC Santa Cruz researchers who made significant contributions to the enormous photomosaic that combines some 600 snapshots taken by the Hubble Space Telescope over more than a decade and 1,000 orbits.

Researchers link mysterious cosmic signals to collapsed stars
An international team of scientists has provided the clearest evidence yet that some fast radio bursts (FRBs)—enigmatic, millisecond-long flashes of radio waves from space—originate from neutron stars, the ultra-dense remnants of massive stars that have exploded in a supernova.

Team discovers ultra-massive galaxies in early Universe that challenge standard cosmology
An international team of astronomers has identified three ultra-massive galaxies—each nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang. The discovery is surprising because it indicates that the formation of stars in the early Universe was far more efficient than previously thought, challenging current models of…

Astronomy postdoc to develop technologies that mold starlight to better detect exoplanets
The Astronomy & Astrophysics Department welcomes postdoctoral scientist Emiel Por, who invents technologies that mold the starlight captured by ground- and space-based telescopes to improve imaging of planetary companions. His work will be supported by the Heising-Simons Foundation’s 51 Pegasi b Fellowship program.
