Exploring the presence of a fifth force at the Galactic Center
The GRAVITY Collaboration, K. Abd El Dayem, R. Abuter +60
Aims: The presence of a Yukawa-like correction to Newtonian gravity is investigated at the Galactic Center, leading to a new upper limit for the intensity of such a correction. Met…
Polarimetry and Astrometry of NIR Flares as Event Horizon Scale, Dynamical Probes for the Mass of Sgr A*
The GRAVITY Collaboration, R. Abuter, N. Aimar +66
We present new astrometric and polarimetric observations of flares from Sgr A* obtained with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope Interferometer…
Using the motion of S2 to constrain scalar clouds around SgrA*
GRAVITY Collaboration, A. Foschi, R. Abuter +67
The motion of S2, one of the stars closest to the Galactic Centre, has been measured accurately and used to study the compact object at the centre of the Milky Way. It is commonly…
Where intermediate-mass black holes could hide in the Galactic Centre: A full parameter study with the S2 orbit
The GRAVITY Collaboration, O. Straub, M. Bauböck +59
In the Milky Way the central massive black hole, SgrA*, coexists with a compact nuclear star cluster that contains a sub-parsec concentration of fast-moving young stars called S-st…
The SEDIGISM survey: Molecular cloud morphology. II. Integrated source properties
K. R. Neralwar, D. Colombo, A. Duarte-Cabral +21
The Structure, Excitation, and Dynamics of the Inner Galactic InterStellar Medium (SEDIGISM) survey has produced high (spatial and spectral) resolution CO (2-1) maps of the…
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…
