On the origin of clustering of frequency ratios in the atoll source 4U 1636-53
Gabriel Torok, Michal Bursa, Jiri Horak +4
A long discussion has been devoted to the issue of clustering of the kHz QPO frequency ratios in the neutron star sources. While the distribution of ratios inferred from an occurre…
Difficulties with the QPOs Resonance Model
Paola Rebusco
High frequency quasi-periodic oscillations (HFQPOs) have been detected in microquasars and neutron star systems. The resonance model suggested by Kluzniak & Abramowicz (2000) expla…
Width of X-ray lines in cooling flows
P. Rebusco, E. Churazov, R. A. Sunyaev +2
The dissipation of turbulent gas motions is one of the likely mechanisms that has been proposed to heat the intracluster medium (ICM) in the cores of clusters and groups of galaxie…
Metal mixing by buoyant bubbles in galaxy clusters
E. Roediger, M. Brueggen, P. Rebusco +2
Using a series of three-dimensional, hydrodynamic simulations on an adaptive grid, we have performed a systematic study on the effect of bubble-induced motions on metallicity profi…
Effect of turbulent diffusion on iron abundance profiles
P. Rebusco, E. Churazov, H. Boehringer +1
We compare the observed peaked iron abundance profiles for a small sample of groups and clusters with the predictions of a simple model involving the metal ejection from the bright…
Epicyclic oscillations of fluid bodies Paper II. Strong gravity
Marek A. Abramowicz, Omer M. Blaes, Jiri Horak +2
Fluids in external gravity may oscillate with frequencies characteristic of the epicyclic motions of test particles. We explicitly demonstrate that global oscillations of a slender…
