Journal ArticleDOI
Measuring Distance and Properties of the Milky Way’s Central Supermassive Black Hole with Stellar Orbits
Andrea M. Ghez,Samir Salim,Nevin N. Weinberg,Nevin N. Weinberg,Jessica R. Lu,Tuan Do,J. K. Dunn,Keith Matthews,Mark Morris,S. Yelda,Eric E. Becklin,T. Kremenek,Milos Milosavljevic,J. Naiman,J. Naiman +14 more
TL;DR: In this paper, the authors reported new precision measurements of the properties of our Galaxy's supermassive black hole, based on astrometric and radial velocity (RV; 2000-2007) measurements from the W. M. Keck 10m telescopes.
Journal ArticleDOI
Stellar Orbits around the Galactic Center Black Hole
Andrea M. Ghez,Samir Salim,Seth D. Hornstein,Angelle Tanner,Jessica R. Lu,Mark Morris,Eric E. Becklin,Gaspard Duchêne +7 more
TL;DR: In this article, a diffraction-limited image of the galactic center was obtained with the W.M.KeckI10mtelescope, which was used to estimate the central dark mass of the galaxy.
Journal ArticleDOI
An Improved Distance and Mass Estimate for Sgr A* from a Multistar Orbit Analysis
Anna Boehle,Andrea M. Ghez,Rainer Schödel,Leo Meyer,S. Yelda,S. Albers,Gregory D. Martinez,Eric E. Becklin,Tuan Do,Jessica R. Lu,Keith Matthews,Mark Morris,Breann N. Sitarski,G. Witzel +13 more
TL;DR: In this paper, the mass and distance of the galaxy's central supermassive black hole Sgr A^* were estimated by using the kinematic measurements from speckle holography and adaptive optics.
Journal ArticleDOI
A disk of young stars at the galactic center as determined by individual stellar orbits
Jessica R. Lu,Andrea M. Ghez,Seth D. Hornstein,Seth D. Hornstein,Mark Morris,Eric E. Becklin,Keith Matthews +6 more
TL;DR: In this article, the authors present new proper motions from the 10 m Keck telescopes for a population of massive, young stars located within 3".5 (0.14 pc) of the supermassive black hole at the Galactic center.
Journal ArticleDOI
Improving galactic center astrometry by reducing the effects of geometric distortion
Sylvana Yelda,Jessica R. Lu,Andrea M. Ghez,Will Clarkson,Will Clarkson,Jay Anderson,Tuan Do,Keith Matthews +7 more
TL;DR: In this paper, the W. M. Keck II 10 m telescope's adaptive optics camera (NIRC2) was used to estimate the proper motion of the galaxy's central stellar cluster.
