Monitoring Stellar Orbits around the Massive Black Hole in the Galactic Center
We present the results of 16 years of monitoring stellar orbits around the massive black hole in center of the Milky Way using high resolution near-infrared techniques. This work refines our previous analysis mainly by greatly improving the definition of the coordinate system, which reaches a longterm astrometric accuracy of ≈ 300μas, and by investigating in detail the individual systematic err...
متن کاملIntermediate-mass Black Hole(s) and Stellar Orbits in the Galactic Center
Many young stars reside within the central half-parsec from SgrA*, the supermassive black hole in the Galactic Center. The origin of these stars remains a puzzle. Recently, Hansen and Milosavljevic (2003, HM) have argued that an Intermediate-Mass Black Hole (IMBH) could have delivered the young stars to the immediate vicinity of SgrA*. Here we focus on the final stages of the HM scenario. Namel...
متن کاملSupermassive Black Hole at the Galactic Center ∗
We derive an analytical expression of a shadow size as a function of a charge in the Reissner – Nordström (RN) metric. Using the derived expression we consider shadows for negative tidal charges and charges corresponding to naked singularities q = Q/M > 1, where Q and M are black hole charge and mass, respectively. An introduction of a negative tidal charge q can describes black hole solutions ...
متن کاملThe Galactic center welcomes black hole immigrants
We simulate the inner 100 pc of the Milky-Way Galaxy to study the formation and evolution of the population of star clusters and intermediate mass black holes. For this study we perform extensive direct N -body simulations of the star clusters which reside in the bulge, and of the inner few tenth of parsecs of the super massive black hole in the Galactic center. In our N -body simulations the d...
متن کاملPerturbations of Intermediate-mass Black Holes on Stellar Orbits in the Galactic Center
We study the shortand long-term effects of an intermediate mass black hole (IMBH) on the orbits of stars bound to the supermassive black hole (SMBH) at the center of the Milky Way. A regularized N-body code including post-Newtonian terms is used to carry out direct integrations of 19 stars in the S-star cluster for 10Myr. The mass of the IMBH is assigned one of four values from 400M⊙ to 4000M⊙,...
