What is the nature of dark energy, a recently discovered dominant constituent of the universe today? Is expansion-accelerating dark energy an intrinsic property of space-time itself or rather a field ...

NASA supercomputer simulations reveal X-ray and gamma-ray signals emitted in the final milliseconds before neutron star mergers, providing insights for future observatories and gravitational-wave ...

When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using ...

Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the most energetic events to take ...

The birth of a gamma-ray burst (GRB) is a stellar event. These incredibly violent blasts are the most energetic explosions in the universe. In just one second, a GRB can release more energy than our ...

The Sun, which provides us with light and heat, is also the site of immense phenomena. In 2017, a powerful solar flare emitted gamma rays whose origin left astronomers puzzled. These emissions ...

A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our galaxy dubbed the “Fermi bubbles”, has puzzled astronomers since it was ...

Roland Crocker receives funding from the Australian Research Council. A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our ...
