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.
