黑洞能量与正则伽马射线暴IV:“长”、“真短”和“假伪装短”伽玛暴
The Blackholic energy and the canonical Gamma-Ray Burst IV: the "long", "genuine short" and "fake - disguised short" GRBs
摘要:
(缩短)[...]在回顾了“火壳模型”的基本特征之后,我们强调了以下新的结果:1)将伽玛暴余辉中的X射线耀斑解释为光学薄火壳与环爆介质(CBM)中孤立云的相互作用; 2)将Norris & Bonnell [...]与一个双星系统在其宿主星系晕中最终合并的起源一致,CBM密度特别低[.]; 3)通过对GRB 050509 B的分析,首次尝试研究一个真正的短GRB,这确实揭示了一个悬而未决的问题:4)通过“诱发引力坍缩“过程解释GRB 060218的GRB-SN关联; 5)第一次尝试理解“阿马蒂关系”的性质,瞬发辐射E_{iso}的各向同性等效辐射能量与宇宙学静止系νF_ν谱峰值能量E_{p,i}之间的唯象相关。此外,还介绍了近形成阶段正负电子等离子体热化的最新进展,以及Kerr-Newman黑洞的电动力学结构。本文还讨论了AGILE和Fermi卫星对伽玛暴中高能现象的可能解释。作为高能过程的一个例子,考察了Enrico Fermi关于超相对论碰撞的工作。很明显,所有的伽玛射线暴物理学都指向超临界电动力学场的存在。从这个意义上讲,我们在重核和中子星核的统一研究方面取得了一些进展,这导致了中子星壳下超临界场的存在。
英文摘要:
(Shortened) [...] After recalling the basic features of the "fireshell model", we emphasize the following novel results: 1) the interpretation of the X-ray flares in GRB afterglows as due to the interaction of the optically thin fireshell with isolated clouds in the CircumBurst Medium (CBM); 2) an interpretation as "fake - disguised" short GRBs of the GRBs belonging to the class identified by Norris & Bonnell [...] consistent with an origin from the final coalescence of a binary system in the halo of their host galaxies with particularly low CBM density [...]; 3) the first attempt to study a genuine short GRB with the analysis of GRB 050509B, that reveals indeed still an open question; 4) the interpretation of the GRB-SN association in the case of GRB 060218 via the "induced gravitational collapse" process; 5) a first attempt to understand the nature of the "Amati relation", a phenomenological correlation between the isotropic-equivalent radiated energy of the prompt emission E_{iso} with the cosmological rest-frame νF_ν spectrum peak energy E_{p,i}. In addition, recent progress on the thermalization of the electron-positron plasma close to their formation phase, as well as the structure of the electrodynamics of Kerr-Newman Black Holes are presented. An outlook for possible explanation of high-energy phenomena in GRBs to be expected from the AGILE and the Fermi satellites are discussed. As an example of high energy process, the work by Enrico Fermi dealing with ultrarelativistic collisions is examined. It is clear that all the GRB physics points to the existence of overcritical electrodynamical fields. In this sense we present some progresses on a unified approach to heavy nuclei and neutron stars cores, which leads to the existence of overcritical fields under the neutron star crust.
