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…
Using VLTI/GRAVITY+ to determine the identity of a third planet candidate in the PDS 70 system
David Trevascus, Wolfgang Brandner, Olga Balsalobre-Ruza +75
Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protop…
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…
First Resolution of Microlensed Images of a Binary-Lens Event
Zexuan Wu, Subo Dong, A. Mérand +72
We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves sh…
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…
GYOTO 2.0: a polarized relativistic ray-tracing code
N. Aimar, T. Paumard, F. H. Vincent +2
Polarized general-relativistic radiative transfer in the vicinity of black holes and other compact objects has become a crucial tool for probing the properties of relativistic astr…
Gravitational waves from bodies orbiting the Galactic Center black hole and their detectability by LISA
Eric Gourgoulhon, Alexandre Le Tiec, Frederic H. Vincent +1
We present the first fully relativistic study of gravitational radiation from bodies in circular equatorial orbits around the massive black hole at the Galactic Center, Sgr A* and…
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…
