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…
Cluster Glimpses with Raven: AO Corrected Near and Mid-Infrared Images of Glimpse C01 and Glimpse C02
T. J. Davidge, D. R. Andersen, O. Lardiere +9
We discuss images of the star clusters GLIMPSE C01 (GC01) and GLIMPSE C02 (GC02) that were recorded with the Subaru IRCS. Distortions in the wavefront were corrected with the RAVEN…
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…
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…
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…
