摘要

微类星体系统发射电磁辐射和高能粒子。由于它们位于我们自己的星系中,所以可以非常详细地观察到它们。尽管如此,它们的许多内部工作原理仍然难以捉摸;因此,模拟作为观测和理论之间的纽带,是非常有用的。本文利用狭义相对论成像计算了模拟微类星体喷流的高能粒子和同步辐射。采用有限射线速度成像算法对流体动力模拟数据进行处理,生成静止观测器上的合成图像。在上述排放模型中加入了水动力模型。然后合成光谱和地图,可以与探测器阵列的观测结果进行比较。作为一种应用,该模型综合观测了微类星体在两个不同时空尺度上的偶发性抛射,一个是在中微子发射区域尺度上,另一个是在同步加速器射电发射尺度上。结果与现有探测器的灵敏度进行了比较。

Simulated Radio and Neutrino Imaging of a Microquasar
Microquasar stellar systems emit electromagnetic radiation and high-energy particles. Thanks to their location within our own galaxy, they can be observed in high detail. Still, many of their inner workings remain elusive; hence, simulations, as the link between observations and theory, are highly useful. In this paper, both high-energy particle and synchrotron radio emissions from simulated microquasar jets are calculated using special relativistic imaging. A finite ray speed imaging algorithm is employed on hydrodynamic simulation data, producing synthetic images seen from a stationary observer. A hydrodynamical model is integrated in the above emission models. Synthetic spectra and maps are then produced that can be compared to observations from detector arrays. As an application, the model synthetically observes microquasars during an episodic ejection at two different spatio-temporal scales: one on the neutrino emission region scale and the other on the synchrotron radio emission scale. The results are compared to the sensitivity of existing detectors.
