微类星体是我们银河系内高能粒子产生的候选场所。由于它们的距离和致密的发射区域限制了对它们的直接观测约束，数值模拟对于将喷流动力学与可能的多信使信号联系起来非常有用。本工作模拟了来自相对论磁流体动力学微类星体喷流的中微子产生，重点关注加速质子与环境光子场相互作用相关的质子光子通道。质子质子相互作用被认为是在稠密环境中可能发生的过程，但在当前计算中未进行建模。将射线追踪程序应用于流体动力学模拟输出，从静止观测者的视角生成合成中微子图像。给出了合成光谱和强度图，并与当前和未来中微子探测器的代表性灵敏度进行了比较。
英文摘要
Microquasars are candidate sites for high energy particle production within our galaxy. Because their distances and compact emission regions limit direct observational constraints, numerical simulations are useful for connecting jet dynamics with possible multi messenger signatures. This work models neutrino production from relativistic magnetohydrodynamic microquasar jets, focusing on the proton photon channel associated with interactions between accelerated protons and ambient photon fields. Proton proton interactions are acknowledged as a possible process in dense environments, but they are not modeled in the present calculation. A ray tracing procedure is applied to the hydrodynamic simulation output to produce synthetic neutrino images from the perspective of a stationary observer. Synthetic spectra and intensity maps are presented and compared with representative sensitivities of current and future neutrino detectors.
