High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
A comparison of next-generation turbulence profiling instruments at Paranal
Ryan Griffiths, Lisa Bardou, Timothy Butterley +6
A six-night optical turbulence monitoring campaign has been carried at Cerro Paranal observatory in February and March, 2023 to facilitate the development and characterisation of t…
MAORY AO performances
Guido Agapito, Cedric Plantet, Lorenzo Busoni +7
The Multi-conjugate Adaptive Optics RelaY (MAORY) should provide 30% SR in K band (50% goal) on half of the sky at the South Galactic Pole. Assessing its performance and the sensit…
ELT instrumentation for seeing-limited and AO-corrected observations: A comparison
Colin Cunningham, Chris Evans, Guy Monnet +1
The next generation of large ground-based optical and infrared telescopes will provide new challenges for designers of astronomical instrumentation. The varied science cases for th…
New challenges for Adaptive Optics: Extremely Large Telescopes
M. Le Louarn, N. Hubin, M. Sarazin +1
The performance of an adaptive optics (AO) system on a 100m diameter ground based telescope working in the visible range of the spectrum is computed using an analytical approach. T…
Laser Guide Star for 3.6m and 8m telescopes: Performances and astrophysical implications
M. Le Louarn, R. Foy, N. Hubin +1
We have constructed an analytical model to simulate the behavior of an adaptive optics system coupled with a sodium laser guide star. The code is applied to a 3.6-m and 8m class te…
