Multiple Star Systems in the Orion Nebula
GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133
This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…
GRAVITY chromatic imaging of Eta Car's core
GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132
Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…
Detection of the gravitational redshift in the orbit of the star S2 near the Galactic centre massive black hole
GRAVITY Collaboration, R. Abuter, A. Amorim +95
The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A* is a sensitive probe of the gravitational field in the Galactic centre. Ne…
LBT/ARGOS adaptive optics observations of z lensed galaxies
M. Perna, M. Curti, G. Cresci +24
Gravitationally lensed systems allow a detailed view of galaxies at high redshift. High spatial- and spectral-resolution measurements of arc-like structures can offer unique constr…
ARGOS at the LBT. Binocular laser guided ground layer adaptive optics
S. Rabien, R. Angel, L. Barl +48
Having completed its commissioning phase, the Advanced Rayleigh guided Ground-layer adaptive Optics System (ARGOS) facility is coming online for scientific observations at the Larg…
Resolving the Host Galaxy of a Distant Blazar with LBT/LUCI1 + ARGOS
Emanuele Paolo Farina, Iskren Y. Georgiev, Roberto Decarli +14
BL Lac objects emitting in the Very High Energy (VHE) regime are unique tools to peer into the properties of the Extragalactic Background Light (EBL). However, due to the typical a…
