Ordered magnetic fields around the 3C 84 central black hole

G. F. Paraschos, J. -Y. Kim, M. Wielgus +279

3C84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region nec…

Characterization of black hole accretion through image moment invariants

A. Jiménez-Rosales, A. I. Yfantis, M. A. Mościbrodzka +1

We apply image moment invariant analysis to total intensity and polarimetric images calculated from general relativistic magnetohydrodynamic simulations of accreting black holes. W…

The GRAVITY Young Stellar Object Survey. VI. Mapping the variable inner disk of HD 163296 at sub-au scales

J. Sanchez-Bermudez, A. Caratti o Garatti, R. Garcia Lopez +53

Protoplanetary disks drive some of the formation process (e.g., accretion, gas dissipation, formation of structures, etc.) of stars and planets. Understanding such physical process…

Constraining particle acceleration in Sgr A* with simultaneous GRAVITY, Spitzer, NuSTAR and Chandra observations

R. Abuter, A. Amorim, M. Bauböck +81

We report the time-resolved spectral analysis of a bright near-infrared and moderate X-ray flare of Sgr A*. We obtained light curves in the -, -, and -bands in the mid- an…

Improved GRAVITY astrometric accuracy from modeling of optical aberrations

GRAVITY Collaboration, R. Abuter, A. Amorim +60

The GRAVITY instrument on the ESO VLTI pioneers the field of high-precision near-infrared interferometry by providing astrometry at the as level. Measurements at such…

Detection of faint stars near SgrA* with GRAVITY

GRAVITY Collaboration, R. Abuter, A. Amorim +58

The spin of the supermassive black hole that resides at the Galactic Centre can in principle be measured by accurate measurements of the orbits of stars that are much closer to Sgr…
