Improved GRAVITY astrometric accuracy from modeling of optical aberrations
GRAVITY Collaboration, R. Abuter, A. Amorim +60
The GRAVITY instrument on the ESO VLTI pioneers the field of high-precision near-infrared interferometry by providing astrometry at the as level. Measurements at such…
Detection of faint stars near SgrA* with GRAVITY
GRAVITY Collaboration, R. Abuter, A. Amorim +58
The spin of the supermassive black hole that resides at the Galactic Centre can in principle be measured by accurate measurements of the orbits of stars that are much closer to Sgr…
The Flux Distribution of Sgr A*
The GRAVITY Collaboration, R. Abuter, A. Amorim +54
The Galactic Center black hole Sagittarius A* is a variable NIR source that exhibits bright flux excursions called flares. The low-flux density turnover of the flux distribution is…
Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole
GRAVITY Collaboration, R. Abuter, A. Amorim +53
The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
A geometric distance measurement to the Galactic Center black hole with 0.3% uncertainty
R. Abuter, A. Amorim, M. Bauboeck +51
We present a 0.16% precise and 0.27% accurate determination of R0, the distance to the Galactic Center. Our measurement uses the star S2 on its 16-year orbit around the massive bla…
