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-…
The full evolution of the type-C QPO in MAXI J1348-630 revealed by Insight-HXMT
X. -L. Wang, Z. Yan, F. -G. Xie +4
Based on abundant data from Insight-HXMT, we conducted a detailed analysis of type-C quasi-periodic oscillations (QPOs) in the black hole X-ray binary MAXI J1348-630. Type-C QPOs w…
Numerical simulations of cold clumps in the hot accretion flows around black holes
Na-Duo Liu, Yu-Heng Sheng, De-Fu Bu +3
Previous numerical simulations have shown that cold clumps can form within hot accretion flows, offering insights into the detailed processes of the state transition in black hole…
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…
An atypical low-frequency QPO detected in the hard state of MAXI J1348-630 with -HXMT
Xin-Lei Wang, Zhen Yan, Fu-Guo Xie +2
Based on the -HXMT archival data, we have detected a new atypical low-frequency quasi-periodic oscillation (LFQPO) in the black hole X-ray binary MAXI J1348630. The new…
