俄歇时代超高能宇宙射线对瞬变源的意义

Implications of Ultra-High-Energy Cosmic Rays for Transient Sources in the Auger Era

Kohta Murase, Hajime Takami

摘要:

我们研究了来自瞬变源的超高能宇宙射线在银河系和星系际空间中的传播。基于最近的观测结果,我们还通过限制视爆发持续时间,估计了瞬态UHECR源速率的上下限和每次爆发所需的各向同性宇宙线能量输入为0.1 Gpc^-3 yr^-1 < rho_0 < 10^3.5 Gpc^-3 yr^-1和10^49.5 ergs < E_HECR^iso < 10^54 ergs,即,UHECR到达时间的分散。基于这些界限,我们讨论了所提出的候选人,如伽马射线暴和活动星系核的影响。

英文摘要:

We study about ultra-high-energy cosmic rays (UHECRs) from transient sources, propagating in the Galactic and intergalactic space. Based on the recent observational results, we also estimate upper and lower bounds on the rate of transient UHECR sources and required isotropic cosmic-ray energy input per burst as 0.1 Gpc^-3 yr^-1 < rho_0 < 10^3.5 Gpc^-3 yr^-1 and 10^49.5 ergs < E_HECR^iso < 10^54 ergs, through constraining the apparent burst duration, i.e., dispersion in arrival times of UHECRs. Based on these bounds, we discuss implications for proposed candidates such as gamma-ray bursts and active galactic nuclei.
