论文摘要
我们研究了Microquasar SS 433射流的GEV-TEV伽马射线发射的辐射和松性场景。TEV光子的发射区与X射线结的发射区域有效地加速了电子。另一方面,光学高密度丝也位于X射线结附近,这可能支持HADRONIC情况。我们通过求解电子和质子的传输方程来计算扩展射流区域的多波长光子光谱。我们发现,HADRONIC和LEPTONIC模型都可以解释观察数据,包括最新的{\ it fermi} LAT结果。辐射场景比Leptonic方案预测更高的能量光子,以及未来的观察结果,例如Cherenkov望远镜阵列(CTA),大型高空空气淋浴天文台(LHAASO)(LHAASO),以及南部的宽阔的宽段 - 射线射击观测(SWGO)可能与这些场景之间的机制区分了Emistaios和Emsision-resision的机制,并将Em emistion与em-spever-Reply-Reckiand(emistion)区分开。基于我们的强烈情况,微Quasar和射电星系之间的类比意味着无线电飞机的X射线结区可能会加速重型核,直至超高能量。
We investigate hadronic and leptonic scenarios for the GeV--TeV gamma-ray emission from jets of the microquasar SS 433. The emission region of the TeV photons coincides with the X-ray knots, where electrons are efficiently accelerated. On the other hand, the optical high-density filaments are also located close to the X-ray knots, which may support a hadronic scenario. We calculate multi-wavelength photon spectra of the extended jet region by solving the transport equations for the electrons and protons. We find that both hadronic and leptonic models can account for the observational data, including the latest {\it Fermi} LAT result. The hadronic scenarios predict higher-energy photons than the leptonic scenarios, and future observations such as with the Cherenkov Telescope Array (CTA), the Large High-Altitude Air Shower Observatory (LHAASO), and the Southern Wide-field Gamma-ray Observatory (SWGO) may distinguish between these scenarios and unravel the emission mechanism of GeV--TeV gamma-rays. Based on our hadronic scenario, the analogy between microquasars and radio galaxies implies that the X-ray knot region of the radio-galaxy jets may accelerate heavy nuclei up to ultrahigh energies.
