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.

Scientists Discover ‘Chiral Phonons’ – Atomic Rotations in a 2-D Semiconductor Crystal

Animation - The atomic motion in a 2-D material, tungsten disulfide, is shown in this animation. In this phonon mode (known as longitudinal or LO), the selenium atoms (yellow) rotate clockwise while the tungsten atoms (blue) are still. (Credit: Hanyu Zhu, et al.)

Applying Machine Learning to the Universe’s Mysteries

Image - The colored lines represent calculated particle tracks from particle collisions occurring within Brookhaven National Laboratory’s STAR detector at the Relativistic Heavy Ion Collider, and an illustration of a digital brain. The yellow-red glow at center shows a hydrodynamic simulation of quark-gluon plasma created in particle collisions. (Credit: Berkeley Lab)
