The advent of data from the Gamma Ray Observatory (GRO), of much higher precision than hitherto, will open up the possibility of deriving more precise results on the presence of 'cosmic ray gradients' in the Galaxy. There will still be a variety of difficulties, however. There are still ...
Interpretation of Cosmic X-ray and Gamma Ray Spectra 来自 Semantic Scholar 喜欢 0 阅读量: 24 作者: JI Trombka 摘要: Changes in the slope of a measured distribution may be explained partially by the effect of the measurement process itself. 关键词: n32300* --physics--cosmic radiation n...
Cosmic ray, a high-speed particle—either an atomic nucleus or an electron—that travels through space. Most of these particles come from sources within the Milky Way Galaxy and are known as galactic cosmic rays (GCRs). The rest of the cosmic rays origin

BEIJING, Nov. 16 (Xinhua) -- China's Large High Altitude Air Shower Observatory (LHAASO), a high-altitude cosmic ray observatory, has released the precise energy spectrum for the highest-energy gamma-ray radiation from the brightest gamma-ray burst (GRB) observed to date. ...
Gamma-ray spectroscopy holds great promise for probing nucleosynthesis in individual stellar explosions via short-lived radioactivity, and for measuring current global Galactic nucleosynthesis with longer-lived radioactivity. The former case was realized first for a Type II supernova when both 56Co and ...

We present a comprehensive study of the gamma-ray luminosity function (GLF) of blazars and their contribution to the extragalactic diffuse gamma-ray background (EGRB). Radio and gamma-ray luminosity correlation is introduced with a modest dispersion, consistent with observations, to take into accoun...
