The 2022 Outburst of IGR J17091–3624: Connecting the Exotic GRS 1915+ 105 to Standard Black Hole X-Ray Binaries
While the standard X-ray variability of black hole X-ray binaries (BHXBs) is stochastic and
noisy, there are two known BHXBs that exhibit exotic" heartbeat"-like variability in their …

Recurrence analysis as a tool to study chaotic dynamics of extreme mass ratio inspiral in signal with noise
G Lukes-Gerakopoulos, O Kopáček - International Journal of …, 2018 - World Scientific
Recurrence analysis is a well-settled method allowing to discern chaos from order and
determinism from noise. We apply this tool to study time series representing geodesic and …
