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…
Discovery of a quasi-periodic oscillation non-harmonically related to the Type-C QPO in the hard intermedidate state of MAXI J1820+070
Pei Jin, Mariano Méndez, Federico García +2
We present a detailed timing analysis of the transition from the hard-intermediate state (HIMS) to the soft-intermediate state (SIMS) in MAXI J1820+070 using NICER observations. Th…
Black-hole X-ray binary Swift J1727.81613 shows simultaneous Type-B and Type-C quasi-periodic oscillations across the hard-intermediate and soft-intermediate states
Pei Jin, Mariano Méndez, Federico García +2
We present a timing analysis of \textit{Insight}-HXMT observations of the black-hole X-ray binary Swift J1727.81613 across a bright soft X-ray flare on 2023 September 19 (MJD 60…
A Hidden Pulse: Uncovering a New Timing Signal in Cygnus X-1 with AstroSat
Sandeep K. Rout, Federico Garcia, Mariano Mendez +4
The study of fast variability properties in X-ray binaries advances our understanding of the physical processes and geometric properties of the accretion flow around the compact ob…
Timing analysis of the black-hole candidate Swift J1727.8-1613: detection of a dip-like feature in the high-energy cross spectrum
Pei Jin, Mariano Méndez, Federico García +3
We present a timing analysis of observations with the Hard X-ray Modulation Telescope of the black hole X-ray transient Swift J1727.8-1613 during its 2023 outburst. We detect, for…
Insight-HXMT observations of the 2023 outburst in Aql X-1
Zhe Yan, Guobao Zhang, Yu-Peng Chen +5
We conducted an analysis of the continuum during the onset and initial decline phases of the 2023 outburst in transient neutron star low-mass X-ray binary Aql X1 using broadband…
The bright black hole X-ray binary 4U 1543-47 during 2021 outburst. A clear state transition from super-Eddington to sub-Eddington accretion revealed by Insight-HXMT
Pei Jin, Guobao Zhang, Yuexin Zhang +9
We present a detailed analysis of the observations with the Hard X-ray Modulation Telescope of the black hole X-ray transient 4U~1543-47 during its outburst in 2021. We find a clea…
The mHz quasi-regular modulations of 4U 1630--47 during its 1998 outburst
Qingchang Zhao, Hongxing Yin, Lian Tao +19
We present the results of a detailed timing and spectral analysis of the quasi-regular modulation (QRM) phenomenon in the black hole X-ray binary 4U 1630--47 during its 1998 outbur…
