Cross-spectral Analysis of the Type-C Quasi-periodic Oscillation Shoulder Component in GX 339-4
Haifan Zhu, Mariano Méndez, Pengcheng Yang +8
We revisit Rossi X-ray Timing Explorer (RXTE) observations of GX~3394 during the rising phase of its 2006/2007 outburst and apply a joint power-density-spectrum (PDS)--cross-spe…
Timing and spectral analysis of the 2025 outburst of 4U 163047 with \textit{NICER}
Haifan Zhu, Mariano Méndez, Xiao Chen +1
We analyzed \textit{NICER} observations of the 2025 outburst of the black hole X-ray binary 4U~163047 to investigate the spectral--timing properties of its transient low-frequen…
Comprehensive X-ray Spectral-timing Analysis of GRS 1915+105 Based on Insight-HXMT Observations
Xiao Chen, Weiping Liu, Wei Wang
GRS 1915+105 has been well studied since its discovery, and is well-known for its complex light curve variability. Using the full currently available Insight-HXMT dataset from July…
Broad-band noises in GX 339-4 during the 2021 outburst observed with Insight-HXMT and NICER
Yong-Jie Jin, Xiao Chen, Hai-Fan Zhu +2
Rapid X-ray variability of GX 3394 including the low-frequency quasi-periodic oscillations (LFQPOs) and broad-band noises have been observed with the Hard X-ray Modulation Teles…
