During the campaign, the LAT instrument aboard the Fermi space observatory detected an increase in high-energy gamma-ray flux with energies up to billions of times greater than visible light.

when its daily-averaged gamma-ray flux increased by a factor of 177 relative to the average flux, while its photon index decreased from the average value of 2.57 to 2.11. These findings represent ...

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 cycle, a gamma-ray wave traveling at the speed of light will ...

Gamma rays are highly energetic photons ... such as neutron stars and black holes. The flux from such sources, together with the timescales on which they vary, can provide strong constraints on the ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed ...

ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
