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…
An atypical X-ray variability component in the black hole candidate AT2019wey
Pengcheng Yang, Mariano Méndez, Sandeep K. Rout +5
Recent studies have revealed a notable timing feature in several black hole X-ray binaries (BHXBs) during the soft-to-hard transition at the outburst decay. Within a narrow frequen…
The evolving properties of the corona of GRS 1915+105: A spectral-timing perspective through variable-Comptonisation modelling
Federico García, Konstantinos Karpouzas, Mariano Méndez +4
The inverse Compton process by which soft photons are up-scattered by hot electrons in a corona plays a fundamental role in shaping the X-ray spectra of black-hole (BH) low-mass X-…
The evolution of the high-frequency variability in the black hole candidate GRS 1915+105 as seen by RXTE
Yuexin Zhang, Mariano Méndez, Federico García +5
GRS 1915+105 can show type-C quasi-periodic oscillations (QPOs) in the power density spectrum. A high-frequency QPO (HFQPO) at 67 Hz has been observed in this source, albeit less o…
