A previously detected, anomalously large X-ray signal is absent in new Hitomi satellite data, setting tighter limits for a dark matter interpretation.

How do scientists know what percentages of the universe are made up of dark matter and dark energy?

Before Hitomi died, it sent back X-ray data that explain how turbulent motions may prevent cooling of hot gas.

Finding ways to handle torrents of data from LSST and LCLS-II will also advance “exascale” computing.

KIPAC researchers mourn the loss of the Hitomi spacecraft but are thrilled about the data it was still able to capture.

The discovery supports a powerful tool for discovering galaxies that are otherwise too distant to observe, and could lead to advances that improve our understanding of dark matter.

It will provide new insights into the physics of black holes, the formation of chemical elements, stars and galaxies, and the evolution of the universe itself.

Dark matter hunters around the world pursue three approaches to look for fingerprints of ghostly WIMPs: on the Earth’s surface, underground and in space.

The emptiest parts of the universe aren’t so empty after all.

Analyzing the motion of X-ray sources could help researchers identify dark matter signals.

Fermi scientist Matthew Wood discusses major improvements to the Fermi Large Area Telescope, including increasing its sensitivity to the equivalent of launching another LAT.

A recent uptick in the discovery of the smallest, oldest galaxies benefits studies of dark matter, galaxy formation and the evolution of the unive
