Astroparticle Physics


UCLA has built a strong and very active group in astrophysics. Comprising eight faculty members and more than forty researchers overall, the group is involved in experimental and theoretical research in the areas of dark matter, high-energy astrophysics (using gamma rays, cosmic rays and neutrinos), and cosmology. Our astrophysics group specializes in a number of interconnected areas of interest. Some areas of research: investigating the origin of the universe, connecting the world of elementary particles with cosmology and astrophysics, dark matter, the physics of neutrinos, gamma rays and cosmic backgrounds, high energy collider physics, and the structure of the universe. 

Faculty research

  • Katsushi Arisaka studies ultra-high-energy (UHE) cosmic rays, particle physics, and is involved in the search for dark matter via projects such as XENON, DarkSide, and XAX.
  • Rene Ong is carrying out research in astroparticle physics, a dynamic and growing field at the interface of physics and astronomy. His current work focuses on the astrophysics of the high-energy universe, as revealed by gamma rays, neutrinos, and cosmic rays, and on the quest to understand the nature of dark matter.
  • Vladimir Vassiliev researches in areas such as ground-based gamma-ray astronomy with VERITAS and Whipple, extragalactic background light, supersymmetric dark matter annihilation in the universe, and cosmic rays in extragalactic objects.
  • Ned Wright investigates infrared astronomy and cosmology using the Wide-field Infrared Survey Explorer (WISE). Professor Wright is also working on the Wilkinson Microwave Anisotropy Probe (WMAP), a mission to follow-up the COBE discovery of fluctuations in the early Universe.
