Detection of orbital motions near the last stable circular orbit of the massive black hole SgrA*
GRAVITY Collaboration, R. Abuter, A. Amorim +57
We report the detection of continuous positional and polarization changes of the compact source SgrA* in high states ('flares') of its variable near- infrared emission with the nea…
Detection of the gravitational redshift in the orbit of the star S2 near the Galactic centre massive black hole
GRAVITY Collaboration, R. Abuter, A. Amorim +95
The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A* is a sensitive probe of the gravitational field in the Galactic centre. Ne…
Optical Distortion in the NACO Imager
P. M. Plewa, S. Gillessen, M. Bauböck +11
In this research note, we present a set of distortion solutions that may be used to correct geometric optical distortion in images taken with the S13 camera of the NACO adaptive op…
