论文摘要

Maxi在2017年爆发期间发现了新的黑洞X射线二进制（BHXRB）Maxi J1535-571。使用第一个中国X射线卫星的观察，硬X射线调制望远镜（用作Insight-Hxmt），我们执行了连接光谱分析（2-150 ke）（2-150 ke）（2-150 ke）。能量光谱提供了探测固有的准周期振荡（QPO）分数RMS光谱（FRS）的基本输入。我们的结果表明，在中间状态下，能量光谱通常与Swift/XRT和Nustar报告的能源一致。但是，QPO FRS变得更加困难，FRS残留物可能表明能量谱中存在额外的幂律分量，或者在高能量处的内在QPO FRS中存在转折。

A new black hole X-ray binary (BHXRB) MAXI J1535-571 was discovered by MAXI during its outburst in 2017. Using observations taken by the first Chinese X-ray satellite, the Hard X-ray Modulation Telescope (dubbed as Insight-HXMT), we perform a joint spectral analysis (2-150 keV) in both energy and time domains. The energy spectra provide the essential input for probing the intrinsic Quasi-Periodic Oscillation (QPO) fractional rms spectra (FRS). Our results show that during the intermediate state, the energy spectra are in general consistent with those reported by Swift/XRT and NuSTAR. However, the QPO FRS become harder and the FRS residuals may suggest the presence of either an additional power-law component in the energy spectrum or a turn-over in the intrinsic QPO FRS at high energies.
