Articles about 'X-ray'

Using X-rays to see inside the human body has revolutionised non-invasive medical diagnostics. However, the dose of X-rays required for imaging is far higher than background levels, due to the poor performance of the detector materials currently available. This can cause harm to patients, and in some cases even cancer.

Astronomers have made a record-breaking measurement of a black hole’s spin, one of two fundamental properties of black holes. NASA’s Chandra X-ray Observatory shows this black hole is spinning slower than most of its smaller cousins. This is the most massive black hole with an accurate spin measurement and gives hints about how some of the universe’s biggest black holes grow.

Professor Andrew Fabian from Cambridge's Institute of Astronomy has been awarded the 2020 Kavli Prize in Astrophysics, one of the world's most prestigious science prizes. 

With its very first – and last – observation, the Hitomi x-ray observatory has discovered that the gas in the Perseus cluster of galaxies is much less turbulent than expected, despite being home to NGC 1275, a highly energetic active galaxy.

Astronomers have observed two black holes in nearby galaxies devouring their companion stars at an extremely high rate, and spitting out matter at a quarter the speed of light.

The Fitzwilliam Museum is marking its bicentenary anniversary celebrations with an exhibition on its remarkable collection of Egyptian coffins. 

Simon Redfern from the Department of Earth Sciences discusses a study that has recreated the conditions experienced during the meteor strike that formed the Barringer Crater in Arizona.

The first 3D reconstruction of the skull of a 360 million-year-old near-ancestor of land vertebrates has been created by scientists.

A new imaging facility offers researchers in Cambridge and beyond the chance to see what lies within objects, without breaking them open.

Astronomers have discovered enormous smooth shapes that look like vapour trails in a gigantic galaxy cluster. These ‘arms’ span half a million light years and provide researchers with clues to a billion years of collisions within the “giant cosmic train wreck” of the Coma cluster.
