Searching for Nearby Supermassive Black Hole Binaries with GRAVITY
GRAVITY Collaboration, K. Abd El Dayem, N. Aimar +82
We present a systematic interferometric search for close supermassive black hole (SMBH) binaries in 20 nearby type 1 active galactic nuclei (AGN) observed with VLTI/\grav. We inves…
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…
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…
Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole
GRAVITY Collaboration, R. Abuter, A. Amorim +53
The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we…
A geometric distance measurement to the Galactic Center black hole with 0.3% uncertainty
R. Abuter, A. Amorim, M. Bauboeck +51
We present a 0.16% precise and 0.27% accurate determination of R0, the distance to the Galactic Center. Our measurement uses the star S2 on its 16-year orbit around the massive bla…
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…
Massive Young Stars in the Galactic Center
H. Bartko
We summarize our latest observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the E…
