Gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. It includes some overlap with X-rays in the el
After a short history of optical transient search and the BeppoSAX discoveries, the main topics included are prompt multiwavelength emission, dark bursts, spectral lines line and continuum variability, the early light curve behaviour, jet breaks, X-ray flares, late afterglow features, polarization, ...

The wavelength of the 57Fe Mössbauer radiation is easily reproducible with an accuracy of at least 10(-11)lambda(M) and could be used as a length standard of atomic dimensions.关键词: nuclear physics and radiation physics wavelengths gamma radiation standards advanced photon source ...
(Science: radiobiology) The length of a single cycle of a wave, usually measured from crest-to-crest. For electromagnetic waves, the wavelength determines the type (radio, infrared, visible, ultraviolet,x-Ray, gamma-ray) ofradiation, in the case ofvisible light, wavelength determines the colour...
In search of the counterpart to the brightest unidentified gamma-ray source 3EG J2020+4017 we report on new X-ray and radio observations of the gamma-Cygni field with the Chandra X-ray Observatory and with the Green Bank Telescope. We also report on reanalysis of archival ROSAT data. With...
Multi-wavelength emission from 3C 66A: clues on its redshift and gamma-ray emission locationThe quasi-simultaneous multi-wavelength emission of TeV blazar 3C 66A is\nstudied by using a one-zone multi-component leptonic jet model. It ... D Yan,Z Fan,Y Zhou,... 被引量: 0发表: 2010年 ...
When the EM wave’s wavelength gets lesser then their energy will increase. The shortest rays are Gamma rays within the spectrum. Sometimes, these rays are used for treating cancer as well as capturing cleared images of diagnostic medicine. These rays are generated within high-energy nuclear blas...
Modern third-generation synchrotron radiation sources provide coherent and extremely bright X-ray beams, but the performance of the optics employed on the beamlines is critical for the X-rays' successful exploitation. The quality of the beam delivered to the sample is limited by the optics' imperfe...
We present observations of the unusually bright and long gamma-ray burst GRB 050820A, one of the best-sampled broadband data sets in the Swift era. The gamma-ray light curve is marked by a soft precursor pulse some 200 s before the main event; the lack of any intervening emission suggest...
