gam′ma ray` n. 1.a highly penetrating photon of high frequency, usu. 1019Hz or more, emitted by an atomic nucleus. 2.a stream of such photons. [1900–05] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Random House, In...
The Gamma-ray Burst Monitor (GBM) on board the Fermi spacecraft provided the energetic radiation measurements. Radio frequency (RF) measurements were obtained from the Global Lightning Dataset (GLD360). Here we show the existence of two categories of TGFs those that were accompanied by quasi-...
Explore gamma rays. Learn the definition of a gamma ray and see its characteristics. Find the sources of gamma rays on Earth and outer space, and...
A new type airborne gamma-ray spectrum stabilization method based on Fast Fourier Transform (FFT) is proposed.The FFT to the gamma-ray spectra is implemented in order to obtain frequency spectra.A quartic polynomial relation existed between the high order harmonic components in the frequency spectra...
Moreover, X-ray data from the Suzaku satellite found a diffuse overionized clump with a jet-like structure south of the GC, i.e., ~200 pc from Sgr A*, suggesting that an energetic ejection of plasma from Sgr A* occurred about 1 Myr ago [9]. Both X-ray observations can be ...
Gamma rays have very short wavelength and quite high frequency of the electromagnetic radiation. Thus, it can penetrate anything except the densest matter. Gamma ray is energetic ionising radiation and thus biologically hazardous. Although gamma rays are electrically neutral, they can ionise atoms ...
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 ...
X-rays and Gamma Rays are high frequency electromagnetic radiation. Gamma rays, X-rays, and some ultraviolet waves have such high energy that they are ionizing, meaning they can knock electrons out of atoms.
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...
The cooling frequency νc is located at frequencies higher than 1 keV (that is νc > 2.4 × 1017 Hz). The glitches at optical ν ~ 1016 Hz are the edge of validity of our dust extinction model. The SN makes a large contribution at late times. See the observations in ...
