Using the motion of S2 to constrain vector clouds around SgrA*

GRAVITY Collaboration, A. Foschi, R. Abuter +53

The dark compact object at the centre of the Milky Way is well established to be a supermassive black hole with mass , but the nature…

Polarization analysis of the VLTI and GRAVITY

GRAVITY Collaboration, F. Widmann, X. Haubois N. Schuhler +59

The goal of this work is to characterize the polarization effects of the VLTI and GRAVITY. This is needed to calibrate polarimetric observations with GRAVITY for instrumental effec…

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…

First spatio-spectral Bayesian imaging of SN1006 in X-ray

Margret Westerkamp, Vincent Eberle, Matteo Guardiani +6

Supernovae are an important source of energy in the interstellar medium. Young remnants of supernovae have a peak emission in the X-ray region, making them interesting objects for…

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…

Cosmology inference at the field level from biased tracers in redshift-space

Julia Stadler, Fabian Schmidt, Martin Reinecke

Cosmology inference of galaxy clustering at the field level with the EFT likelihood in principle allows for extracting all non-Gaussian information from quasi-linear scales, while…

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…

Accelerations of stars in central 2-7 arcsec from Sgr A*

A. Young, S. Gillessen, T. de Zeeuw +10

This work presents the results from extending the long-term monitoring program of stellar motions within the Galactic Center to include stars with separations of 2 - 7 arcseconds f…
