Exploring the presence of a fifth force at the Galactic Center
The GRAVITY Collaboration, K. Abd El Dayem, R. Abuter +60
Aims: The presence of a Yukawa-like correction to Newtonian gravity is investigated at the Galactic Center, leading to a new upper limit for the intensity of such a correction. Met…
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…
