Broadband Properties of the Harmonic of Type-C Quasi-periodic Oscillation in MAXI J1348-630
Xin-Lei Wang, Zhen Yan, Jun-Feng Wang +3
Harmonics are common features of quasi-periodic oscillations (QPOs) in black hole X-ray binaries; however, their physical origins remain poorly understood. Using broadband Insight-…

Transitional Dynamics: Unveiling the Coexistence and Interplay of Type-B and Type-C QPOs in MAXI J1348-630
Xinlei Wang, Zhen Yan, Fu-Guo Xie +3
Based on broadband timing analysis of Insight-HXMT and NICER data from the 2019 outburst of the black hole X-ray binary (BHXRB) MAXI J1348-630, we report the detection of the coexi…
