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…
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…
`imaka - a ground-layer adaptive optics system on Maunakea
Mark Chun, Olivier Lai, Douglas Toomey +12
We present the integration status for `imaka, the ground-layer adaptive optics (GLAO) system on the University of Hawaii 2.2-meter telescope on Maunakea, Hawaii. This wide-field GL…
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…
