Laboratory Results and Status Update for Pathfinder at LBT, The LINC-NIRVANA NGS Ground- Layer AO Subsystem
Derek Kopon, Al Conrad, Thomas Bertram +20
The full LINC-NIRVANA instrument will be one of the most complex ground-based astronomical systems ever built. It will consist of multiple subsystems, including two multi-conjugate…
Near-infrared wavefront sensing for the VLT interferometer
Stefan Hippler, Wolfgang Brandner, Yann Clénet +11
The very large telescope (VLT) interferometer (VLTI) in its current operating state is equipped with high-order adaptive optics (MACAO) working in the visible spectrum. A low-order…
The GRAVITY Coudé Infrared Adaptive Optics (CIAO) system for the VLT Interferometer
Sarah Kendrew, Stefan Hippler, Wolfgang Brandner +19
GRAVITY is a second generation instrument for the VLT Interferometer, designed to enhance the near-infrared astrometric and spectro-imaging capabilities of VLTI. Combining beams fr…
Validating the Local Volume Mapper acquisition and guiding hardware
Maximilian Häberle, Thomas M. Herbst, Peter Bizenberger +13
The Local Volume Mapper (LVM) project is one of three surveys that form the Sloan Digital Sky Survey V. It will map the interstellar gas emission in a large fraction of the souther…
The MICADO first light imager for the ELT: overview, operation, simulation
Richard Davies, João Alves, Yann Clénet +98
MICADO will enable the ELT to perform diffraction limited near-infrared observations at first light. The instrument's capabilities focus on imaging (including astrometric and high…
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…
