The dark mass signature in the orbit of S2
Gernot Heißel, Thibaut Paumard, Guy Perrin +1
Aims. We explore a strategy for how the Schwarzschild and mass precessions can be separated from each other despite their secular interference, by pinpointing their signatures with…
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…
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…
The hot dust in the heart of NGC 1068's torus: A 3D radiative model constrained with GRAVITY/VLTi
Pierre Vermot, Yann Clénet, Damien Gratadour +5
The central region of NGC 1068 is one of the closest and most studied Active Galactic Nucleus. It is known to be of type 2, meaning that its accretion disk is obscured by a large a…
Mapping the Galactic centre's dark cluster via Resonant Relaxation
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon +4
Supermassive black holes in the centre of galaxies dominate the gravitational potential of their surrounding stellar clusters. In these dense environments, stars follow nearly Kepl…
