伽玛暴的同步辐射自吸收过程及各向同性能量-峰值能量基本关系

Synchrotron Self-Absorption Process in GRBs and the Isotropic Energy - Peak Energy Fundamental Relation

M. Yu. Piotrovich, Yu. N. Gnedin, T. M. Natsvlishvili

摘要:

伽马射线暴(GRB)的峰值亮度(或辐射热能量)之间是否存在强相关性是GRB物理学中最令人感兴趣的问题之一。这种相关性尚未被理解。在这里,我们表明,这种相关性可以解释的框架内同步自吸收(SSA)机制的伽玛暴即时发射。我们在$B\sim 10^{14} (10^3/Γ)^3 (1+z)^2$水平上估计了中央发动机的磁场强度,其中$Γ$是火球的洛伦兹因子。

英文摘要:

The existence of strong correlation between the peak luminosity (and/or bolometric energetics) of Gamma Ray Bursts (GRB) is one of the most intrigue problem of GRB physics. This correlation is not yet understood. Here we demonstrate that this correlation can be explained in framework of synchrotron self-absorption (SSA) mechanism of GRB prompt emission. We estimate the magnetic field strength of the central engine at the level $B\sim 10^{14} (10^3/Γ)^3 (1+z)^2$, where $Γ$ is the Lorentz factor of fireball.
