TL;DR: In this article, the authors presented a 0.16% precise and 0.27% accurate determination of R0, the distance to the Galactic Center using the star S2 on its 16-year orbit around the massive black hole Sgr A* that they followed astrometrically and spectroscopically for 27 years.

TL;DR: In this article, the authors present a list of authors who have contributed to the work of the authors of this paper: Akiyama, Kazunori; Algaba, Juan Carlos; Alberdi, Antxon; Alef, Walter; Anantua, Richard; Asada, Keiichi; Azulay, Rebecca; Baczko, Anne-Kathrin; Ball, David; Balokovic, Mislav; Barrett, John; Benson, Bradford A.; Bintley, Dan; Blackburn, Lindy; Blundell

TL;DR: In this article, the authors reported the detection of continuous positional and polarization changes of SgrA* in high states of its variable near- infrared emission with the near-infrared GRAVITY-Very Large Telescope Interferometer (VLTI) beam-combining instrument.

TL;DR: In this article, the first detection of the GR Schwarzschild precession (SP) in S2's orbit was reported, which is mainly a kink between the pre-and post-pericentre directions of motion, relative to the corresponding Kepler orbit.

TL;DR: In this article, the authors present a list of the authors who contributed to the development of this work, including: Akiyama, Kazunori; Algaba, Juan Carlos; Alberdi, Antxon; Anantua, Richard; Asada, Keiichi; Azulay, Rebecca; Baczko, Anne-Kathrin; Ball, David; Balokovic, Mislav; Barrett, John; Benson, Bradford A; Bintley, Dan; Bunderwood, Nissim; Bower, Geoffrey C;
