Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY
J. J. Wang, A. Vigan, S. Lacour +101
We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 as precision astromet…
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 TP3-WFS: a new guy in town
Carlos Colodro-Conde, Sergio Velasco, Roberto López +11
The TP3-WFS (Two Pupil Plane Positions Wavefront Sensor) is, to the best of the authors' knowledge, the first physical implementation of the geometrical wavefront reconstruction al…
Processing diffraction-limited images through innovative Super-Resolution techniques
E. Quevedo, S. Velasco, C. Colodro-Conde +10
In the ELTs era, where the need for versatile and innovative solutions to produce very high spatial resolution images has become a major issue, the search of synergies with other s…
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…
