Adam G. Riess,Adam G. Riess,Lucas M. Macri,Samantha L. Hoffmann,Daniel Scolnic,Daniel Scolnic,Stefano Casertano,Alexei V. Filippenko,Brad E. Tucker,Brad E. Tucker,Mark J. Reid,David O. Jones,Jeffrey M. Silverman,Ryan Chornock,Peter Challis,Wenlong Yuan,Peter J. Brown,Ryan J. Foley +17 more
TL;DR: In this paper, the authors used the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) to reduce the uncertainty in the local value of the Hubble constant from 3.3% to 2.4%.
Journal ArticleDOI

Mark J. Reid,Karl M. Menten,Andreas Brunthaler,Xingwu Zheng,Thomas M. Dame,Ye Xu,Yuefang Wu,B. Zhang,Alberto Sanna,Mayumi Sato,Kazuya Hachisuka,Y. K. Choi,K. Immer,L. Moscadelli,K. L. J. Rygl,A. Bartkiewicz +15 more
TL;DR: In this paper, the authors estimate the radius to the Galactic center, R-0, to be 8.34 +/- 0.16 kpc, a circular rotation speed at the Sun, Theta(0), to be 240 +/- 8 km s(-1), and a rotation curve that is nearly flat.
Journal ArticleDOI
Trigonometric parallaxes of massive star-forming regions. vi. galactic structure, fundamental parameters, and noncircular motions
Mark J. Reid,Karl M. Menten,X. W. Zheng,Andreas Brunthaler,Luca Moscadelli,Y. Xu,Y. Xu,Bing Zhang,M. Sato,Mareki Honma,Tomoya Hirota,K. Hachisuka,Y. K. Choi,G. A. Moellenbrock,Anna Bartkiewicz +14 more
TL;DR: In this article, the authors used the Very Long Baseline Array and the Japanese VLBI Exploration of Radio Astronomy project to measure trigonometric parallaxes and proper motions of masers found in high-mass star-forming regions across the Milky Way.
Journal ArticleDOI

TL;DR: Ten years of high-resolution astrometric imaging allow us to trace two-thirds of the orbit of the star currently closest to the compact radio source (and massive black-hole candidate) Sagittarius A* and show that the star is on a bound, highly elliptical keplerian orbit around Sgr A*.
Journal ArticleDOI
The distance to the Orion Nebula
TL;DR: In this paper, the authors used the Very Long Baseline Array (VLBA) to measure the parallax of stars of the Orion Nebula Cluster showing non-thermal radio emission, and determined the distance to the cluster to be 414 ± 7 pc.
