Continuation of the X-ray monitoring of Sgr A*: the increase in bright flaring rate confirmed
E. Mossoux, B. Finociety, J. -M. Beckers +1
The supermassive black hole Sagittarius A* (Sgr A*) is located at the dynamical center of the Milky Way. In a recent study of the X-ray flaring activity from Sgr A* using Chandra,…
Rossby Wave Instability and High-Frequency Quasi-Periodic Oscillations in accretion discs orbiting around black holes
Peggy Varniere, Fabien Casse, Frederic Vincent
The rather elusive High-Frequency Quasi-Periodic Oscillations(HFQPO) observed in the X-ray lightcurve of black holes have been seen in a wide range of frequencies, even within one…
Impact of inclination on quasi-periodic oscillations from spiral structures
P. Varniere, F. H. Vincent
Context. Quasi-periodic oscillations (QPOs) are a common feature of the power spectrums of X-ray binaries. Currently it is not possible to unambiguously differentiate the large num…
Quasi-periodic oscillations from Rossby Wave Instability
F. H. Vincent, P. Varniere, H. Meheut +3
We study the Rossby wave instability model of high-frequency quasi-periodic oscillations (QPO) of microquasars. We show ray-traced light curves of QPO within this model and discuss…
