Numerical relativity uses supercomputers to simulate conditions occuring at the start of the universe, answering some of the ...
Abstract: This article investigates the influence of high-energy secondary electrons on a Ka-band TM03 relativistic backward-wave oscillator (RBWO) using the particle-in-cell (PIC) simulation code ...
Abstract: We present a novel particle-grid scheme for simulating bubble and foam flow. At the core of our approach lies a particle representation that combines the computational nature of moving least ...
The particle collider smashes together atomic nuclei—comprised of particles called protons and neutrons—to break them into their smaller components. Tiffany Bowman / Brookhaven National Laboratory For ...
The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...
A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog ...

I peeked in on the house-sized particle detector known as STAR just after it took its last-ever snapshot of one of the most extreme types of fireball ever created. Inside, the conditions just after ...
