The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?

J. Varga, M. Hogerheijde, R. van Boekel +133

Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…

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…

Dynamically important magnetic fields near the event horizon of Sgr A*

GRAVITY Collaboration, A. Jiménez-Rosales, J. Dexter +53

We study the time-variable linear polarisation of Sgr A* during a bright NIR flare observed with the GRAVITY instrument on July 28, 2018. Motivated by the time evolution of both th…

The Flux Distribution of Sgr A*

The GRAVITY Collaboration, R. Abuter, A. Amorim +54

The Galactic Center black hole Sagittarius A* is a variable NIR source that exhibits bright flux excursions called flares. The low-flux density turnover of the flux distribution is…

Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole

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

The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we…
