Wavelet analysis of MAXI J1535โ571 with <i>Insight-HXMT</i>
ABSTRACT In this paper, wavelet analysis is used to study the spectral-timing properties of MAXI J1535โ571 observed by the Hard X-ray Modulation Telescope (Insight-HXMT). Low-frequency quasi-periodic oscillations (QPOs) are detected in nine observations. Based on wavelet analysis, the time intervals with QPOs and non-QPOs are isolated, and the corresponding spectra โฆ
