Compelling evidence of a link between the lags of the quasi-periodic oscillations and the radio jet in the black-hole X-ray binary GRS 1915+105
Candela Bellavita, Mariano Méndez, Federico García +5
GRS 1915+105 is one of the most studied black-hole X-ray binaries, known for its extreme variability and rich phenomenology. Previous studies of this source with the Rossi X-ray Ti…
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…
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…
A NICER view of the corona through time-dependent Comptonization of the quasi-periodic oscillations in nine black-hole X-ray binaries
Yuexin Zhang, Mariano Méndez, James F. Steiner +12
We present a systematic study of the evolution of the corona geometry in nine black hole X-ray binaries (BHXRBs) using archival data from NICER. We identify 171 observations exhibi…
The nature of an imaginary quasi-periodic oscillation in the soft-to-hard transition of MAXI J1820+070
Candela Bellavita, Mariano Méndez, Federico García +2
A recent study shows that if the power spectra (PS) of accreting compact objects consist of a combination of Lorentzian functions that are coherent in different energy bands but in…
A NICER look at the jet-like corona of MAXI J1535-571 through type-B quasi-periodic oscillations
Yuexin Zhang, Mariano Méndez, Federico García +7
MAXI J1535-571 is a black-hole X-ray binary that in 2017 exhibited a very bright outburst which reached a peak flux of up to 5 Crab in the 2-20 keV band. Given the high flux, sever…
