GRAVITY acquisition camera: characterization results

Narsireddy Anugu, Paulo Garcia, Antonio Amorim +10

GRAVITY acquisition camera implements four optical functions to track multiple beams of Very Large Telescope Interferometer (VLTI): a) pupil tracker: a lenslet images…

The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales

GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69

51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…

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…

Determining sub-parsec supermassive black hole binary orbits with infrared interferometry

J. Dexter, D. Lutz, T. T. Shimizu +12

Radial velocity monitoring has revealed the presence of moving broad emission lines in some quasars, potentially indicating the presence of a sub-parsec binary system. Phase-refere…

Direct confirmation of the radial-velocity planet Pic c

M. Nowak, S. Lacour, A. -M. Lagrange +90

Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…

The spatially resolved broad line region of IRAS 09149-6206

GRAVITY Collaboration, A. Amorim, W. Brandner +41

We present new near-infrared VLTI/GRAVITY interferometric spectra that spatially resolve the broad Br emission line in the nucleus of the active galaxy IRAS 09149-6206. We use t…
