Cosmic plasma was supposed to rule out dark photons. Simulations say otherwise
A major limit on dark photon dark matter may be far weaker because early-universe plasma stops absorbing energy much sooner ...

Scientists use AI to simulate universes at scale
As we delve deeper into the cosmos, artificial intelligence (AI) is becoming an indispensable tool, enabling scientists to simulate universes on a scale never seen before. This novel approach is not ...
A massive simulation of the cosmos and a nod to the next generation of computing A team of physicists and computer scientists from the U.S. Department of Energy’s (DOE) Argonne National Laboratory ...
Cosmological simulations of dark matter halos form the backbone of our understanding of large-scale structure in the Universe. By numerically evolving millions to billions of particles under gravity, ...
Cosmological simulations have become indispensable tools for understanding the assembly of galaxies within the framework of a ΛCDM Universe. By numerically integrating the coupled equations of gravity ...
The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic ...
Cosmologist Francisco “Paco” Villaescusa-Navarro has a problem. “We are spending billions of dollars in ground and space telescopes to decipher the mysteries of the universe,” he explains, “but we are ...
A strategy borrowed from generative AI — train cheaply on the familiar, then fine-tune on the hard problem — can cut the number of expensive physics simulations needed by nearly a factor of ten. But a ...
