Instead of the dust lanes and star-filled patches of the visible-light Milky Way, Fermi's whole-sky map features a thin, bright stripe of gamma rays emanating from the galactic plane, most of it coming from interstellar gas, pulsars, and stellar-mass black holes.
If our eyes could see gamma rays, the sky would never appear dark.
The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a cyclic flood of gamma rays, the highest-energy form of light.
Since the era of the EGRET instrument on the Compton Gamma Ray Observatory in the 1990s, it has been discussed whether outbursts of radio emission are physically connected to similar events occurring at gamma rays" Anton Zensus, Director at the Max Planck Institute for Radio Astronomy (MPIfR) and Fermi Affiliated Scientist said.
Astronomers don't think the gamma rays arise from the same regions as the radio waves, so these emissions likely take slightly different paths, with correspondingly different delays and amplifications, as they travel through the lens.
Gamma-ray bursts are mammoth explosions featuring jets of high-speed particles that spawn gamma rays.
The electromagnetic spectrum ranges from radio waves (some of which have photon energies of 10-9 eV), through visible light (a few eV), to higher-energy x-rays (10 keV and up) and gamma rays (mostly 100 keV and up).
Many astronomers believe that as the star fades away and becomes a black hole, it shoots gamma rays into space.
24]Na has a lifetime of 15 h and emits more than 4 MeV of gamma rays when it decays.
Until recently, gamma rays have been the exclusive source of food irradiation in this country.
It is important that the gamma rays emitted are low energy as the procedure is diagnostic and the tissue should not be damaged from the radiation exposure.
For about 40 seconds, the satellite measured a sharp pulse of gamma rays.
