Effects of a disk structure on stellar motion at the Galactic Center
Arianna Foschi, Frederic H. Vincent, Thibaut Paumard +1
Stellar orbits are key for probing the environment of the supermassive black hole at the Galactic Center, Sagittarius A. So far, the mass around SgrA has been assumed to be…
Improving constraints on the extended mass distribution in the Galactic Center with stellar orbits
The GRAVITY Collaboration, Karim Abd El Dayem, Roberto Abuter +66
Studying the orbital motion of stars around Sagittarius A* in the Galactic Center provides a unique opportunity to probe the gravitational potential near the supermassive black hol…
A dynamical measure of the black hole mass in a quasar 11 billion years ago
R. Abuter, F. Allouche, A. Amorim +124
Tight relationships exist in the local universe between the central stellar properties of galaxies and the mass of their supermassive black hole. These suggest galaxies and black h…
Performance of astrometric detection of a hotspot orbiting on the innermost stable circular orbit of the galactic centre black hole
F. H. Vincent, T. Paumard, G. Perrin +3
The galactic central black hole Sgr A* exhibits outbursts of radiation in the near infrared (so-called IR flares). One model of these events consists in a hotspot orbiting on the i…
