P-REx II. Off-line Performance on VLTI/GRAVITY

Saavidra Perera, Jörg-Uwe Pott, Julien Woillez +4

For sensitive optical interferometry, it is crucial to control the evolution of the optical path difference (OPD) of the wavefront between the individual telescopes of the array. T…

The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits

GRAVITY Collaboration, R. Abuter, N. Aimar +62

The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…

Deep Images of the Galactic Center with GRAVITY

GRAVITY Collaboration, R. Abuter, N. Aimar +65

Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…

Flaremodel: An open-source Python package for one-zone numerical modelling of synchrotron sources

Y. Dallilar, S. von Fellenberg, M. Bauböck +13

Synchrotron processes, the radiative processes associated with the interaction of energetic charged particles with magnetic field, are of interest in many areas in astronomy, from…

The mass of Beta Pictoris c from Beta Pictoris b orbital motion

S. Lacour, J. J. Wang, L. Rodet +96

We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…

A geometric distance to the supermassive black Hole of NGC 3783

GRAVITY Collaboration, A. Amorim, M. Bauböck +45

The angular size of the broad line region (BLR) of the nearby active galactic nucleus (AGN) NGC 3783 has been spatially resolved by recent observations with VLTI/GRAVITY. A reverbe…
