Using the Multi-Object Adaptive Optics demonstrator RAVEN to observe metal-poor stars in and towards the Galactic Centre
Masen Lamb, Kim Venn, David Andersen +16
The chemical abundances for five metal-poor stars in and towards the Galactic bulge have been determined from H-band infrared spectroscopy taken with the RAVEN multi-object adaptiv…
William Herschel Telescope site characterization using the MOAO pathfinder CANARY on-sky data
O. A. Martin, C. M. Correia, E. Gendron +8
Canary is the Multi-Object Adaptive Optics (MOAO) pathfinder for the future MOAO-assisted Integral-Field Units (IFU) proposed for Extremely Large Telescopes (ELT). The MOAO concept…
PSF reconstruction validated using on-sky CANARY data in MOAO mode
O. A. Martin, C. M. Correia, E. Gendron +8
In preparation of future Multi-Object Spectrographs (MOS) whose one of the major role is to provide an extensive statistical studies of high redshifted galaxies surveyed, the demon…
Statistics of Turbulence Parameters at Maunakea using multiple wave-front sensor data of RAVEN
Yoshito H. Ono, Carlos M. Correia, Dave R. Andersen +5
Prior statistical knowledge of the atmospheric turbulence is essential for designing, optimizing and evaluating tomographic adaptive optics systems. We present the statistics of th…
Natural guide-star processing for wide-field laser-assisted AO systems
Carlos M. Correia, Benoit Neichel, Jean-Marc Conan +5
Sky-coverage in laser-assisted AO observations largely depends on the system's capability to guide on the faintest natural guide-stars possible. Here we give an up-to-date status o…
Multi time-step wave-front reconstruction for tomographic Adaptive-Optics systems
Yoshito H. Ono, Masayuki Akiyama, Shin Oya +5
In tomographic adaptive-optics (AO) systems, errors due to tomographic wave-front reconstruction limit the performance and angular size of the scientific field of view (FoV), where…
