A Galactic centre gravitational-wave Messenger
Marek Abramowicz, Michal Bejger, Eric Gourgoulhon +1
Our existence in the Universe resulted from a rare combination of circumstances. The same must hold for any highly developed extraterrestrial civilisation, and if they have ever ex…
Accurate ray tracing of realistic neutron star atmospheres for constraining their parameters
F. H. Vincent, M. Bejger, A. Rozanska +9
Thermal dominated X-ray spectra of neutron stars in quiescent transient X-ray binaries and neutron stars that undergo thermonuclear bursts are sensitive to mass and radius. The mas…
Comparing timelike geodesics around a Kerr black hole and a boson star
M. Grould, Z. Meliani, F. H. Vincent +2
The second-generation beam combiner at the Very Large Telescope (VLT), GRAVITY, observes the stars orbiting the compact object located at the center of our galaxy, with an unpreced…
Circular geodesics and thick tori around rotating boson stars
Z. Meliani, F. H. Vincent, P. Grandclément +3
Accretion disks play an important role in the evolution of their relativistic inner compact objects. The emergence of a new generation of interferometers will allow to resolve thes…
Equilibrium solutions of relativistic rotating stars with mixed poloidal and toroidal magnetic fields
Koji Uryu, Eric Gourgoulhon, Charalampos Markakis +3
Stationary and axisymmetric solutions of relativistic rotating stars with strong mixed poloidal and toroidal magnetic fields are obtained numerically. Because of the mixed componen…
Constraining the nature of the Galactic center black hole Sgr A* with present and future observations
F. H. Vincent, E. Gourgoulhon, O. Straub +4
The Galactic center is an ideal laboratory to study strong-field general relativistic phenomena, as the supermassive black hole Sgr A* has the biggest angular Schwarzschild radius…
