WFIRST will add pieces to the dark matter puzzle

The true nature of dark matter is one of the biggest mysteries in the universe. Scientists are trying to determine what exactly dark matter is made of so they can detect it directly, but our current understanding has so many ...

Physicists solve 2,000-year-old optical problem

A trio of physicists from the National Autonomous University of Mexico and Tec de Monterrey has solved a 2,000-year-old optical problem—the Wasserman-Wolf problem. In their paper published in the journal Applied Optics, ...

Direct atom-resolved imaging of magnetic materials

In conventional electron microscopes, performing atomic-resolution observations of magnetic materials is particularly difficult because high magnetic fields are inevitably exerted on samples inside the magnetic objective ...

CosmoGAN: Training a neural network to study dark matter

As cosmologists and astrophysicists delve deeper into the darkest recesses of the universe, their need for increasingly powerful observational and computational tools has expanded exponentially. From facilities such as the ...

A new filter to better map the dark universe

The earliest known light in our universe, known as the cosmic microwave background, was emitted about 380,000 years after the Big Bang. The patterning of this relic light holds many important clues to the development and ...
