Discovery of a star sensitive to the spin of Sgr A*

K. Abd El Dayem, R. Abuter, N. Aimar +85

The paper reports the discovery of a faint main‑sequence star (S301) on an 8.7‑year, highly eccentric orbit around the Milky Way’s central black hole, whose high velocity makes its…

Spatially resolved broad line region in a quasar at z=4: Dynamical black hole mass and prominent outflow

GRAVITY+ Collaboration, K. Abd El Dayem, N. Aimar +92

We present the first near-infrared interferometric data of a QSO at z=4. The K-band observations were performed with GRAVITY+ on the VLTI using all four UTs, detecting a differenti…
