论文摘要
黑洞Maxi J1820+070在其2018年爆发期间被发现，并在电磁频谱上进行了广泛的监测。在发现相对论无线电飞机之后，我们获得了2018年11月至2019年5月在2018年11月至2019年5月进行的四次Chandra X射线观测，并与VLA和Meerkat阵列进行了无线电观测。我们报告发现与以相对论速度移动的无线电飞机相关的X射线源，并且可能在晚期下降。喷气机的宽带光谱与从与星际介质相互作用的冲击物产生的冲击的颗粒的同步辐射一致。从喷气机的X射线观测值中估计的最小内部能量为$ \ sim 10^{41} $ erg，明显大于单独的无线电耀斑计算的能量，这表明大多数能量可能不会在小尺度上辐射，而是通过延迟时间互动释放。
The black hole MAXI J1820+070 was discovered during its 2018 outburst and was extensively monitored across the electromagnetic spectrum. Following the detection of relativistic radio jets, we obtained four Chandra X-ray observations taken between 2018 November and 2019 May, along with radio observations conducted with the VLA and MeerKAT arrays. We report the discovery of X-ray sources associated with the radio jets moving at relativistic velocities with a possible deceleration at late times. The broadband spectra of the jets are consistent with synchrotron radiation from particles accelerated up to very high energies (>10 TeV) by shocks produced by the jets interacting with the interstellar medium. The minimal internal energy estimated from the X-ray observations for the jets is $\sim 10^{41}$ erg, significantly larger than the energy calculated from the radio flare alone, suggesting most of the energy is possibly not radiated at small scales but released through late-time interactions.
