论文摘要
在爱因斯坦的相对论中，假设真空中的光速对于所有观察者都是常数。然而，量子重力的效果可能带来光速的能量依赖性，以及一系列对来自伽马射线爆发（GRB）和主动银河系核（AGNS）的高能量光子事件的研究，这表明光速变化$ v（e）= c \ left（1-e / e / e / e _ {\ mathrm {\ mathrm {\ Mathrm {\ Mathrm {\ Mathrm {\ Mathrm {\ right）$ $ e _ {\ mathrm {lv}} = 3.6 \ times 10^{17}〜\ mathrm {gev} $或一个绑定的$ e _ {\ Mathrm {lv}} \ ge 3.6 \ ge 3.6 \ times 10^{17} {17}〜{17}〜\ mathrm {geev} $。从新观察到的伽马射线爆发Grb 221009a中，我们发现，费米 - 拉特检测到的99.3〜GEV光子与Fermi-GBM和HEB在光曲线中检测到的急剧尖峰相吻合，在上述光速变化下，这表明了这种高度的光子效果，这与Ementy Photity相同，这是一个敏锐的光孔。 来源。因此，在伽马射线爆发的迅速发射过程中，费米 - 拉特检测到的最高能量光子事件可能被认为是宇宙空间中光速修饰的线性形式修饰的可选信号。
It is postulated in Einstein's relativity that the speed of light in vacuum is a constant for all observers. However, the effect of quantum gravity could bring an energy dependence of light speed, and a series of studies on high-energy photon events from gamma-ray bursts (GRBs) and active galactic nuclei (AGNs) suggest a light speed variation $v(E)=c\left(1-E / E_{\mathrm{LV}}\right)$ with $E_{\mathrm{LV}}=3.6 \times 10^{17} ~\mathrm{GeV}$ or a bound $E_{\mathrm{LV}} \ge 3.6 \times 10^{17} ~\mathrm{GeV}$. From the newly observed gamma-ray burst GRB 221009A, we find that a 99.3~GeV photon detected by Fermi-LAT is coincident with the sharp spike in the light curves detected by both Fermi-GBM and HEBS under the above scenario of light speed variation, suggesting an option that this high-energy photon was emitted at the same time as a sharp spike of low-energy photon emission at the GRB source. Thus this highest energy photon event detected by Fermi-LAT during the prompt emission of gamma-ray bursts might be considered as an optional signal for the linear form modification of light speed in cosmological space.
