Improving constraints on the Yukawa correction at the Galactic Center with multiple stellar orbits
GRAVITY+ Collaboration, :, A. Foschi +78
We investigate the presence of a Yukawa-like correction () to Newtonian gravity at the Galactic Center, using a multi-star fitting code, including the newly…
Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
Residing in the center of the Milky Way, Sgr A* is the closest massive black hole (MBH). Its vicinity has allowed measuring individual stellar orbits around it. The stars act as te…
Using the motion of S2 to constrain vector clouds around SgrA*
GRAVITY Collaboration, A. Foschi, R. Abuter +53
The dark compact object at the centre of the Milky Way is well established to be a supermassive black hole with mass , but the nature…
Polarimetry and Astrometry of NIR Flares as Event Horizon Scale, Dynamical Probes for the Mass of Sgr A*
The GRAVITY Collaboration, R. Abuter, N. Aimar +66
We present new astrometric and polarimetric observations of flares from Sgr A* obtained with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope Interferometer…
First results from the JWST Early Release Science Program Q3D: Powerful quasar-driven galactic scale outflow at
Andrey Vayner, Nadia L. Zakamska, Yuzo Ishikawa +25
Quasar-driven galactic outflows are a major driver of the evolution of massive galaxies. We report observations of a powerful galactic-scale outflow in a extremely red, intri…
Confronting a Thin Disk-Wind Launching Mechanism of Broad-Line Emission in AGN with GRAVITY Observations of Quasar 3C 273
Kirk Long, Jason Dexter, Yixian Cao +7
Quasars show a remarkable degree of atomic emission line-broadening, an observational feature which, in conjunction with a radial distance estimate for this emission from the nucle…
