Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients can appear when
the source is in the low-hard and hard-intermediate states. The spectral-timing evolution of …

Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst.
Based on the X-ray spectrum and variability, this evolution can be divided into three …

Abstract Swift J1727. 8–1613 is a black hole X-ray binary newly discovered in 2023. We
perform spectral analysis with simultaneous Insight-HXMT, NICER, and NuSTAR …

Although low-frequency quasiperiodic oscillations (LFQPOs) are commonly detected in the
X-ray light curves of accreting black hole X-ray binaries, their origin still remains elusive. In …

Insight-HXMT is the first Chinese X-ray astronomical mission. With a 1–250 keV bandpass,
an energy resolution of 150 eV at 6 keV, and without being subject to pile-up distortions, it is …

In this paper, wavelet analysis is used to study the spectral-timing properties of MAXI J1535–
571 observed by the Hard X-ray Modulation Telescope (Insight-HXMT). Low-frequency …

We investigate systematically four outbursts of black hole system GX 339-4 observed by the
Rossi X-ray Timing Explorer (RXTE) in both spectral and timing domains and find that these …

We present a systematic analysis of type C quasiperiodic oscillation (QPO) observations of
H1743-322 throughout the Rossi X-ray Timing Explorer era. We find that, while different …

Using wavelet analysis and power density spectrum, we investigate two transient quasi-
periodic oscillations (QPOs) observed in MAXI J1535− 571 observed with Insight-HXMT …

We studied the 2018 outburst of the black hole transient H 1743− 322 with a series of Insight-
HXMT, NICER, and NuSTAR observations, covering the 1–120 keV band. With our broad …
