Black hole spin inferred from 3:2 epicyclic resonance model of high-frequency quasi-periodic oscillations
E. Sramkova, G. Torok, A. Kotrlova +5
Estimations of black hole spin in the three Galactic microquasars GRS 1915+105, GRO J1655-40, and XTE J1550-564 have been carried out based on spectral and timing X-ray measurement…
Oscillations of tori in the pseudo-Newtonian potential
Eva Sramkova, Ulf Torkelsson, Marek A. Abramowicz
Context. The high-frequency quasi-periodic oscillations (HF QPOs) in neutron star and stellar-mass black hole X-ray binaries may be the result of a resonance between the radial and…
QPOs in microquasars: the spin problem
Gabriel Torok, Marek A. Abramowicz, Zdenek Stuchlik +1
In the Galactic microquasars with double peak kHz quasi-periodic oscillations (QPOs), the ratio of the two frequencies is 3:2. This supports the suggestion that double peak kHz QPO…
