  1. Gamma-ray astronomy is a subfield of astronomy where scientists observe and study celestial objects and phenomena in outer space which emit cosmic electromagnetic radiation in the form of gamma rays [nb 1], i.e. photons with the highest energies (above 100 keV) at the very shortest wavelengths.

  2. A luminous supersoft X-ray source (SSXS, or SSS) is an astronomical source that emits only low energy (i.e., soft) X-rays. Soft X-rays have energies in the 0.09 to 2.5 keV range, whereas hard X-rays are in the 1–20 keV range. [1] SSSs emit few or no photons with energies above 1 keV, and most have effective temperature below 100 eV.

  4. Superweiche Röntgenquelle. Superweiche Röntgenquelle ( englisch Super Soft X-Ray Source, SSS) bezeichnet ein astronomisches Objekt, dessen elektromagnetische Strahlung überwiegend im Bereich der weichen Röntgenstrahlung (von 0,1 bis 2,5 keV) emittiert wird. Die meisten SSS sind in extragalaktischen Systemen nachgewiesen worden, da innerhalb ...

    Cygnus X-1 (abbreviated Cyg X-1) is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole. It was discovered in 1965 during a rocket flight and is one of the strongest X-ray sources detectable from Earth, producing a peak X-ray flux density of 2.3 × 10 −23 W/(m 2 ⋅Hz) (2.3 × 10 3 jansky).

NASA's Chandra X-ray Observatory is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes.

  7. The observation of minutes to hours of X-ray flashes after a short gamma-ray burst is consistent with small particles of a primary object like a neutron star initially swallowed by a black hole in less than two seconds, followed by some hours of lesser energy events, as remaining fragments of tidally disrupted neutron star material (no longer neutronium) remain in orbit to spiral into the ...
