论文摘要
最近，Pierre Auger和望远镜阵列合作报道了有力的证据表明，最高能量宇宙射线与附近的Starburst星系之间存在相关性，其全球意义在$4.6σ$之间。众所周知，这些星系中央区域中的超新星和风的集体效应驱动了银河尺度的超级风，可以使热量热并加速环境界面或圆形气体。在先前的工作中，我们表明，对于合理的源参数，Starburst驱动的超级风波可以成为超高能量宇宙射线加速的载体。在本文中，我们评估了人们可以在多大程度上接近考古``反向''的问题，即从当今的宿主星系发射IR发射的超级风向进化的特性。我们表明，Galaxy NGC 891的外部限制可以为超高能量宇宙射线的Starburst驱动的超级风模型提供``吸烟枪支证据''。
Very recently, the Pierre Auger and Telescope Array collaborations reported strong evidence for a correlation between the highest energy cosmic rays and nearby starburst galaxies, with a global significance post-trial of $4.6σ$. It is well known that the collective effect of supernovae and winds from massive stars in the central region of these galaxies drives a galactic-scale superwind that can shock heat and accelerate ambient interstellar or circumgalactic gas. In previous work we showed that, for reasonable source parameters, starburst-driven superwinds can be the carriers of ultra-high-energy cosmic ray acceleration. In this paper we assess the extent to which one can approach the archaeological ``inverse'' problem of deciphering properties of superwind evolution from present-day IR emission of their host galaxies. We show that the Outer Limits galaxy NGC 891 could provide ``smoking gun evidence'' for the starburst-driven superwind model of ultra-high-energy cosmic rays.
