CERN Ceremony Marks Groundbreaking for Accelerator Upgrade Involving U.S. National Labs

Photo - A collaboration among several U.S. national laboratories has been working on superconducting magnets that will be integral to a planned high-luminosity upgrade for CERN's Large Hadron Collider. (Credit: Reidar Hahn/Fermi National Accelerator Laboratory)

From Moon Rocks to Space Dust: Berkeley Lab's Extraterrestrial Research

Photo - A blue crystal recovered from a meteorite that fell near Morocco in 1998. The scale bar represents 200 microns (millionths of a meter). Such crystals, which have been studied at Berkeley Lab, have been found to contain liquid water and complex organic compounds. (Credit: Queenie Chan/The Open University, U.K.)

Tiny Distortions in Universe’s Oldest Light Reveal Clearer Picture of Strands in Cosmic Web

Illustration - In this illustration, the trajectory of cosmic microwave background light is bent by structures known as filaments that are invisible to our eyes, creating an effect known as weak lensing captured by the Planck satellite (left), a space observatory. Researchers used computers to study the weak lensing signals and produce a map of these filaments, which typically span hundreds of light years in length.

Can Strongly Lensed Type Ia Supernovae Resolve One of Cosmology’s Biggest Controversies?

Image - This composite of two astrophysics simulations shows a Type Ia supernova (purple disc) expanding over different microlensing magnification patterns (colored fields). Because individual stars in the lensing galaxy can significantly change the brightness of a lensed event regions of the supernova can experience varying amounts of brightening and dimming, which scientists believed would be a problem for cosmologists measuring time delays. Using detailed computer simulations at NERSC, astrophysicists showed that this would have a small effect on time-delay cosmology. (Credit: Danny Goldstein/UC Berkeley)

Solving the Dark Energy Mystery: A New Assignment for a 45-Year-Old Telescope

Photo - A view inside the dome at the Mayall Telescope in Arizona. The telescope’s 2-meter corrector barrel will be removed and replaced with a new corrector barrel for the Dark Energy Spectroscopic Instrument. DESI’s installation will begin soon at the telescope.

Creating a World of Make-Believe to Better Understand the Real Universe

Image - This plot shows a thin slice through a mock galaxies catalog. The blue and green points are “bright” and “faint” galaxies simulated for the Dark Energy Spectroscopic Instrument’s Bright Galaxy Survey, and the red points show galaxies that are brighter than the magnitude limit of the Sloan Digital Sky Survey.
