Disk warping and black hole X-ray binaries I. Tentative unification of low-frequency quasi-periodic oscillations
Gregoire Marcel, Samuel Turner, Benjamin Ricketts +6
X-ray binaries exhibit complex variability patterns studied in the power-spectrum. These include the broad-band noise (BBN) components and various types of narrow components called…
The strong Fe K line and spin of the black-hole X-ray binary MAXI J1631-479
Andrzej A. Zdziarski, Swadesh Chand, Gulab Dewangan +5
We study the transient black hole binary MAXI J1631--479 in its soft spectral state observed simultaneously by the NICER and NuSTAR instruments. Its puzzling feature is the presenc…
Spins of Black Holes in X-ray Binaries and the Tension with the Gravitational Wave Measurements
Andrzej A. Zdziarski, Gregoire Marcel, Alexandra Veledina +2
We review current challenges in understanding the values and origin of the spins of black holes in binaries. Thanks to recent advances in astrophysical instrumentation, the spins c…
Flip-flop QPO changes during state transitions: a case study of GX339-4 and theoretical discussion
D. J. K. Buisson, G. Marcel, V. López-Barquero +3
We analyse the 2021 outburst from the black hole X-ray binary GX339-4 observed by NICER around the hard to soft transition, when the system exhibits flip-flops between two distinct…
