The bubbles display a spectrum with higher peak energies than the diffuse gamma-ray glow seen throughout the sky. In addition, the bubbles display sharp edges in Fermi LAT data. Both of these ...

So seeing a diffuse gamma ray glow was not that surprising since we expect things to look smeared out at these energies. But we can measure the total energy, and we have a pretty good idea of what ...

The gamma-ray sky Gamma-ray astronomy can be traced back 50 years to a paper by the late US theoretical astrophysicist Philip Morrison, who argued that most of the visible light upon which traditional ...

New analyses of the x-ray and gamma-ray emissions from the center of the Milky Way galaxy, the Andromeda galaxy, and the Perseus galaxy cluster have detected significant signs of two possible dark ...

The research paper, “Probing Intergalactic Neutral Hydrogen by the Lyman-Alpha Red Damping Wing of Gamma-Ray Burst 130606A Afterglow Spectrum at z=5.913”, by Tomonori Totani, Kentaro Aoki ...

A Self-Guided Tour of the Electromagnetic Spectrum Gamma rays It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one ...

Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual ...

Gamma rays fall in the range of the EM spectrum above soft X-rays. Gamma rays have frequencies greater than about 10^19 cycles per second, or hertz (Hz), and wavelengths of less than 100 ...

The Sun emits electromagnetic radiation across a broad spectrum, including visible, infrared, microwave, radio, ultraviolet, X-ray, and gamma-ray wavelengths. Visible light, comprising wavelengths ...
