Levitating atmospheres of Eddington-luminosity neutron stars
Maciek Wielgus, Aleksander Sadowski, Wlodek Kluzniak +2
We construct models of static, spherically symmetric shells supported by the radiation flux of a luminous neutron star in the Schwarzschild metric. The atmospheres are disconnected…
Hořava's quantum gravity illustrated by embedding diagrams of the Kehagias-Sfetsos spacetimes
Kateřina Goluchová, Konrad Kulczycki, Ronaldo S. S. Vieira +3
Possible astrophysical consequences of the Hořava quantum gravity theory have been recently studied by several authors. They usually employ the Kehagias-Sfetsos (KS) spacetime whic…
Quasi-periodic oscillations from relativistic hydrodynamical slender tori
B. Mishra, F. H. Vincent, A. Manousakis +3
We simulate an oscillating purely hydrodynamical torus with constant specific angular mo- mentum around a Schwarzschild black hole. The goal is to search for quasi-periodic oscil-…
Constraints on an Annihilation Signal from a Core of Constant Dark Matter Density around the Milky Way Center with H.E.S.S
HESS Collaboration, A. Abramowski, F. Aharonian +223
An annihilation signal of dark matter is searched for from the central region of the Milky Way. Data acquired in dedicated ON/OFF observations of the Galactic center region with H.…
High frequency oscillations in outbursts of Kerr-metric slim disks
Li Xue, Wlodek Kluzniak, Aleksander Sadowski +2
We numerically investigate the thermally unstable accretion disks around black holes. We adopt an evolutionary viscous stress equation to replace the standard alpha-prescription ba…
