New Angles on Jet Scattering in the Quark-Gluon Plasma at RHIC and the LHC

An artistic representation of a liquidlike fireball of "quark-gluon plasma" (QGP) created in a collision of two gold ions at the Relativistic Heavy Ion Collider (RHIC). This collision has also produced a correlated spray of particles (a "jet") back-to-back with a photon (wavy purple line). Scientists from RHIC's STAR Collaboration showed that interactions of the jet particles cause the QGP to splash sideways, like the wake behind a power boat, enabling them to measure properties of the plasma.

Magnets Could Unlock a New Way to Detect Gravitational Waves

Gravitational waves (blue lines) that pass through a magnet (orange) will cause it to oscillate, thereby generating an oscillating magnetic field that could be detected. In this way, large magnets can operate as Weber Bars. Image Credit: Nick Rodd, Berkeley Lab

Researchers Make Key Gains in Unlocking the Promise of Compact X-ray Free-Electron Lasers

Jeroen van Tilborg, Sam Barber, and Carl Schroeder lean over the chicane magnets that connect the laser plasma accelerator (behind them) to the downstream undulator. The electron beam excursion in the chicane allows for remnant laser light to be blocked, while also temporally separating electrons of different energies to reduce the sliced energy spread.
