Gamma-Ray Bursts Subset and Supernova Remnants Low Radio-Frequency Turnover 来自 Semantic Scholar 喜欢 0 阅读量: 22 作者: X Liu 摘要: Durations of gamma-ray bursts (GRB's) are featured by >2s subset and <2s one, with initial corresponding energy ratio being 20:1. It is found that ...
Gamma-Ray Observatories are scientific facilities in space that detect and study high-energy gamma-ray emissions from celestial sources, providing valuable data on a wide range of astronomical phenomena such as Active Galactic Nuclei and blazars.

KGRS is designed to monitor GRBs in five energy bins, plus high gain and low gain gamma-ray LaBr3 background spectra sensors, and a Boron-Loaded Plastic Scintillator (BLPS) shielding detector. The KGRS count data in all channels are integrated over a period of 10 s. Figure 1 ...
Isolation of X-rays and gamma rays by a common alternative wavelength (or equivalent frequency or photon energy). Below any wavelength is defined as noncombustion, such as 10−11 m (0.1 A), called a gamma ray. This parameter allocates photons in an ambiguous range, but it is possible ...
However, no measurements of the full extension in space and time of a gamma-ray-glow region and their occurring frequency have been reported so far. Here we show that tropical thunderclouds over ocean and coastal regions commonly emit gamma rays for hours over areas up to a few thousand ...

The stabilizer is effective in preventing the thermoplastic polymer from decreasing in material properties or yellowing when irradiated with η-ray. The polymer containing the stabilizer suffers little deterioration in color tone during molding, has an excellent hue, is reduced in molecular weight ...
We have studied in detail the 0.15-15 GHz radio spectrum of the gamma-ray binary LS 5039 to look for a possible turnover and absorption mechanisms at low frequencies, and to constrain the physical properties of its emission. We have analysed two archival
γ-ray is an electromagnetic radiation with extremely high frequency and high photon energy. As a promising radiation source, it has a broad range of applications in material science, nuclear physics, antimatter physics1–3, logistics for providing shipment security, medicine4 for sterilizing medical...
