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…

Multiple Star Systems in the Orion Nebula

GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133

This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…

GRAVITY chromatic imaging of Eta Car's core

GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132

Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…

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…
