AO3k at Subaru: First on-sky results of the facility extreme-AO
Julien Lozi, Kyohoon Ahn, Hannah Blue +12
The facility adaptive optics of the Subaru Telescope AO188 recently received some long-awaited upgrades: a new 3224-actuator deformable mirror (DM) from ALPAO (hence the name chang…
SHARPEST: The atmospheric turbulence profiling experiment using Shack-Hartmann sensor at the Subaru telescope
Hajime Ogane, Yoshito Ono, Yosuke Minowa +5
Atmospheric turbulence profile plays an important role in designing and operating adaptive optics (AO) systems with multiple laser guide stars. To obtain representative free atmosp…
AO3000 at Subaru: Combining for the first time a NIR WFS using First Light's C-RED ONE and ALPAO's 64x64 DM
Julien Lozi, Kyohoon Ahn, Christophe Clergeon +7
After 16 years of on-sky operation, Subaru Telescope's facility adaptive optics AO188 is getting several major upgrades to become the extreme-AO AO3000 (3000 actuators in the pupil…
High Contrast and High Angular Imaging at Subaru Telescope
Olivier Guyon, Kyohoon Ahn, Masayuki Akiyama +10
Adaptive Optics projects at Subaru Telescope span a wide field of capabilities ranging from ground-layer adaptive optics (GLAO) providing partial correction over a 20 arcmin FOV to…
Imaging based feedback cooling of a levitated nanoparticle
Yosuke Minowa, Keisuke Kato, Shoki Ueno +4
Imaging-based detection of the motion of the levitated nanoparticles complements a widely-used interferometric detection method, providing a precise and robust way to estimate the…
Multiple MgII Absorption Systems in the Lines of Sight to Quadruply Lensed Quasar H1413+1143
Katsuya Okoshi, Yosuke Minowa, Nobunari Kashikawa +6
We find multiple Mg II absorption systems at redshift z=1.66, 2.069, and 2.097 in the spatially resolved spectra of the quadruply gravitationally lensed quasar H1413+1143 utilizing…
