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 ...

Gravitationally lensed quasars

The path of light is bent by mass, an effect predicted by Einstein's theory of gravity, and when a massive galaxy or cluster lies along our line-of-sight to a more distant galaxy its matter will act as a lens to image the ...

Measuring white dwarf masses with gravitational lensing

Measuring the mass of a celestial body is one of the most challenging tasks in observational astronomy. The most successful method uses binary systems because the orbital parameters of the system depend on the two masses. ...

Natural telescope sets new magnification record

Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution—gravitational lensing, predicted by Albert Einstein and observed many times by astronomers. Now, an ...
