Lense-Thirring precession of neutron-star accretion flows: Relativistic versus classical precession
Gabriel Török, Martin Urbanec, Monika Matuszková +5
The vertical (Lense-Thirring) precession of the innermost accretion flows has been discussed as a sensitive indicator of the rotational properties of neutron stars (NSs) and their…
Timing of accreting neutron stars with future X-ray instruments: towards new constraints on dense matter equation of state
V. Karas, K. Klimovicova, D. Lancova +7
The Enhanced X-ray Timing and Polarimetry (eXTP) mission is a space mission to be launched in the late 2020s that is currently in development led by China in international collabor…
Simple analytic formula relating the mass and spin of accreting compact objects to their rapid X-ray variability
Gabriel Török, Andrea Kotrlová, Monika Matuszková +4
Following the previous research on epicyclic oscillations of accretion disks around black holes (BHs) and neutron stars (NSs), a new model of high-frequency quasi-periodic oscillat…
Mass of the active galactic nucleus black hole XMMUJ134736.6+173403
Kateřina Goluchová, Gabriel Török, Eva Šrámková +3
A recent study of the X-ray source XMMUJ134736.6+173403 has revealed a strong quasi-periodic modulation of the X-ray flux. The observation of two quasiperiodic oscillations (QPOs)…
Super-spinning compact objects and models of high-frequency quasi-periodic oscillations observed in Galactic microquasars. II. Forced resonances
Andrea Kotrlová, Eva Šrámková, Gabriel Török +2
In our previous work (Paper I) we applied several models of high-frequency quasi-periodic oscillations (HF QPOs) to estimate the spin of the central compact object in three Galacti…
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…
