The universe is filled with light with many different energies. Part of it is invisible to us, especially the extremely energetic gamma rays, which can only be produced in the most extreme environments of our universe, for example supermassive black holes, stars that explode or astrophysic jets. To "see" [...]
Scientists uncover 450 mysterious gamma-ray sources in space
Astronomers have uncovered roughly 450 sources of powerful gamma rays in a part of the energy spectrum that has long been difficult to study. The discovery opens a new window on some of the universe’s most extreme objects, including black holes and the remnants of exploding stars. The international research team examined 14 years of […]
The radiation of energy-rich cosmic objects has so far been particularly difficult to detect in part of the gamma spectrum. A new catalogue of the Fermi space telescope now lists 450 sources between 20 and 200 megaelectronvolts, including 60 previously uncataloged gamma-ray sources without a known counterpart. The data could help the origin of these signals and the acceleration of particles in space [...] The article New Fermi catalogue shows 60…
