Probing the properties of the Milky Way's central supermassive black hole with stellar orbits
Abstract We report new precision measurements of the properties of our Galaxy's supermassive black hole. Based on astrometric (1995-2007) and radial velocity (2000-2007) measurements from the W. M.

Mapping photodissociation and shocks in the vicinity of Sgr A
We have obtained maps of the molecular emission within the central five arcminutes (12 pc) of the Galactic center (GC) in selected molecular tracers: SiO(2-1), HNCO(5_{0,5}-4_{0,4}), and the J=1-->0
Gravitational Lensing of Stars in the Central Arcsecond of Our Galaxy
In the neighborhood of Sgr A*, several stars (S2, S12, S14, S1, S8, and S13) enjoy an accurate determination of their orbital parameters. General relativity predicts that the central black hole acts
A population of dust-enshrouded objects orbiting the Galactic black hole
Observations of four additional G objects, all lying within 0.04 parsecs of the black hole and forming a class that is probably unique to this environment are reported.
Investigating the Binarity of S0-2: Implications for its Origins and Robustness as a Probe of the Laws of Gravity around a Supermassive Black Hole
The star S0-2, which orbits the supermassive black hole (SMBH) in our Galaxy with a period of 16 years, provides the strongest constraint on both the mass of the SMBH and the distance to the Galactic
Colliding with G2 near the Galactic Centre: a geometrical approach
The object G2 will pass within ∼100 au from Sgr A* in 2014. Due to its very short periapse, the study of the dynamical evolution of this object in the short-term future may offer some insight into
The Hypervelocity Star SDSS J090745.0+024507 Is Variable
We present high-precision photometry of the hypervelocity star SDSS J090745.0+024507 (hereafter HVS), which has a Galactic rest-frame radial velocity of v = 709 km s-1, and thus has likely been

An Update on Monitoring Stellar Orbits in the Galactic Center
Using 25 years of data from uninterrupted monitoring of stellar orbits in the Galactic Center, we present an update of the main results from this unique data set: a measurement of mass and distance


Sagittarius A* “Visual Binaries”: A Direct Measurement of the Galactocentric Distance
We present a new geometrical method for measuring the distance to the Galactic center (R0) by solving for the Keplerian orbit of individual stars bound to the black hole associated with Sgr A* from
The Supermassive Black Hole at the Center of the Milky Way
We report the detection of a variable point source, imaged at L' (3.8 μm) with the Keck II 10 m telescope's adaptive optics system, that is coincident to within 18 mas (1 σ) of the Galaxy's central
The Motion of Stars near the Galactic Center: A Comparison of the Black Hole and Fermion Ball Scenarios
After a discussion of the properties of degenerate fermion balls, we analyze the orbits of the stars S0-1 and S0-2, which have the smallest projected distances to Sgr A*, in the supermassive black
The Proper Motion of Sagittarius A*. I. First VLBA Results
We observed Sgr A* and two extragalactic radio sources nearby in angle with the VLBA over a period of 2 yr and measured relative positions with an accuracy approaching 0.1 mas. The apparent proper
Stellar proper motions in the central 0.1 PC of the galaxy
We report the first results of a programme to measure proper motions of stars in the innermost core of the Galaxy. From high-resolution near-infrared imaging over the last four years we have
The First Measurement of Spectral Lines in a Short-Period Star Bound to the Galaxy’s Central Black Hole: A Paradox of Youth
We have obtained the first detection of spectral absorption lines in one of the high-velocity stars in the vicinity of the Galaxy's central supermassive black hole. Both Brγ (2.1661 μm) and He I
The accelerations of stars orbiting the Milky Way's central black hole
Measurements of the accelerations of three stars from the central radio source Sagittarius A* increase the inferred minimum mass density in the central region of the Galaxy by an order of magnitude relative to previous results, and localize the dark mass to within 0.05 ± 0.04 arcsec of the nominal position of Sgr A*.
Stellar orbits near Sagittarius A
The SHARP/NTT stellar proper motion data now cover an interval from 1992 to 2000 and allow us to determine orbital accelerations for some of the most central stars of the Galaxy. We confirm the
