First direct detection of an exoplanet by optical interferometry; Astrometry and K-band spectroscopy of HR8799 e
S. Lacour, M. Nowak, J. Wang +85
To date, infrared interferometry at best achieved contrast ratios of a few times on bright targets. GRAVITY, with its dual-field mode, is now capable of high contrast obs…

Test of Einstein equivalence principle near the Galactic center supermassive black hole
A. Amorim, M. Bauböck, J. P. Berger +49
During its orbit around the four million solar mass black hole Sagittarius A* the star S2 experiences significant changes in gravitational potential. We use this change of potentia…

Modelling the black hole silhouette in Sgr A* with ion tori
Odele Straub, Frederic H. Vincent, Marek A. Abramowicz +2
We calculate the "observed at infinity" image and spectrum of the accretion structure in Sgr A*, by modelling it as an optically thin, constant angular momentum ion torus in hydrod…
