  • John Belz researchRide the Lightning

    John Belz, Associate Professor of Physics & Astronomy, became interested in cosmic rays in the late 1990s. “There was an interesting, unsolved problem at that time,” said Belz. “Cosmic rays were observed with energies greater than predicted – something we hadn’t expected to see. Eventually the problem was resolved by Utah’s High Resolution ‘Fly’s Eye’ detector.” The “Fly's Eye” detector was an ultra-high energy cosmic ray observatory located in the west desert of Utah from 1997 to 2006.

  • Stars, Galaxies, and the History of the Universe Stars, Galaxies, and the History of the Universe

    For nearly 20 years, scientists and universities around the world – including the University of Utah – have been part of the Sloan Digital Sky Survey (SDSS). The unprecedented project has helped map millions of stars and galaxies and created the most detailed three-dimensional images of the universe.

  • Daniel WikSolving a Cosmic Mystery

    Daniel Wik, Assistant Professor of Physics & Astronomy, helped conclude a study using data from NASA’s NuSTAR space telescope to confirm that Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is accelerating particles to ultra-high energies. Some of the particles could reach Earth as cosmic rays.

  • Riding the (Quantum Magnetic) WaveRiding the (Quantum Magnetic) Wave

    In 1991, University of Utah chemist Joel Miller developed the first magnet with carbon-based, or organic, components that was stable at room temperature. It was a great advance in magnetics, and he’s been exploring the applications ever since. Twenty-five years later, physicists Christoph Boehme and Valy Vardeny demonstrated a method to convert quantum waves into electrical current. They too, knew they’d discovered something important, but didn’t know its application. Now those technologies have come together and could be the first step towards a new generation of faster, more efficient and more flexible electronics.

  • Anil SethFaculty Spotlight: Anil Seth

    Anil Seth, Associate Professor of Physics and Astronomy, fell in love with astronomy in high school in Lincoln, Nebraska. Now, when he isn’t teaching classes at the U, or mentoring graduate students, he spends his time searching for black holes at the centers of low-mass galaxies.

  • SDSS-VNext Generation Astronomical Survey To Map The Entire Sky

    The next generation of the Sloan Digital Sky Survey (SDSS-V), will move forward with mapping the entire sky following a $16 million grant from the Alfred P. Sloan Foundation. The grant will kickstart a groundbreaking all-sky spectroscopic survey for a next wave of discovery, anticipated to start in 2020. The University of Utah has been a key member of the SDSS collaboration since 2009, and all of the survey data will be processed and stored at the U’s Center for High-Performance Computing. The Sloan Digital Sky Survey has been one of the most successful and influential surveys in the history of astronomy, creating the most detailed three-dimensional maps of the universe ever made, with deep multi-color images of one third of the sky, and spectra for more than three million astronomical objects. The survey’s fifth generation will build off the earlier SDSS incarnations, but will break new ground by pioneering all-sky spectroscopic observations, taking the spectra of another 6 million objects, and monitoring many of the objects’ changes over time.

  • Shanti DeemyadFaculty Spotlight: Shanti Deemyad

    Shanti Deemyad, an Associate Professor of Physics and Astronomy, recently helped solve a long-standing mystery about lithium, the first element in the periodic table that is metallic at ambient conditions. Lithium, which is a key element in electronics and battery technology, has played an important role in the development of modern condensed matter theories. The crystal structure of materials at zero pressure and temperature is one of their most basic properties. Until now, it was thought that a complex arrangement of lithium atoms, observed during cooling in the laboratory, was its lowest energy state. But the idea baffled theoretical physicists since lithium has only three electrons and therefore should have a simple atomic structure.
