伽马射线暴可能是蓝移的残余辐射束
Gamma ray bursts may be blueshifted bundles of the relic radiation
摘要：
提出了一个假说，即伽马射线暴（GRB）可能是由最后一个散射时期产生的氢和氦的发射辐射发生蓝移而产生的。蓝移机制由这样的Lemaittre-Tolman（L-T）模型提供，其中爆炸时间函数$t_B(r)$不是处处恒定。蓝移发生在\textit{radial}射线上，该射线在$\dril{t_B} r \neq 0$的区域上发射。本文提出了一个适用于此目的的L-T模型，并说明了它是如何解释伽玛暴的观测性质的，有些性质只是定性地解释。
英文摘要：
A hypothesis is proposed that the gamma-ray bursts (GRBs) may arise by blueshifting the emission radiation of hydrogen and helium generated during the last scattering epoch. The blueshift mechanism is provided by such a Lemaître -- Tolman (L--T) model, in which the bang-time function $t_B(r)$ is not everywhere constant. Blueshift arises on \textit{radial} rays that are emitted over regions where $\dril{t_B} r \neq 0$. The paper presents an L--T model adapted for this purpose and shows how it accounts for the observed properties of the GRBs, some properties are accounted for only qualitatively.
