Berkeley, CA — Weak gravitational lensing is a uniquely promising way to learn how much dark matter there is in the Universe and how its distribution has evolved since the distant past. New work by a ...

Think you can figure out a way to unlock one of the biggest secrets of the universe? The recently launched third Gravitational Lensing Accuracy Testing challenge (GREAT3) is giving researchers the ...

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard ...

The FLAMINGO super simulation maps the universe from its earliest moments but finds galaxies cluster less than cosmological ...

FLAMINGO simulation maps the universe but reveals a puzzling mismatch: galaxies cluster less than theory predicts.

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...

ABSTRACT.Future orbiting observatories will survey large areas of sky in order to constrain the physics of dark matter and dark energy using weak gravitational lensing and other methods. Lossy ...

“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of ...

Predicted by Einstein and discovered in 1979, gravitational lensing helps astrophysicists understand the evolving shape of the universe. On March 29, 1979, high in the Quinlan Mountains in the Tohono ...

The Universe is a bit bent. You’d think that light would travel in straight lines, going directly from point A to point B. But it’s more complicated than that. Space is curved, warped, distorted by ...

Clumps and clusters of galaxies exhibit gravitational effects on the light-and-matter behind them due to the effects of weak gravitational lensing. In addition, arcs, multiple images of the same ...
