SCExAO, an instrument with a dual purpose: perform cutting-edge science and develop new technologies
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +31
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is an extremely modular high-contrast instrument installed on the Subaru telescope in Hawaii. SCExAO has a dual…
Characterizing Vibrations at the Subaru Telescope for the Subaru Coronagraphic Extreme Adaptive Optics instrument
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +6
Vibrations are a key source of image degradation in ground-based instrumentation, especially for high-contrast imaging instruments. Vibrations reduce the quality of the correction…
Demonstration of an efficient, photonic-based astronomical spectrograph on an 8-m telescope
N. Jovanovic, N. Cvetojevic, B. Norris +11
We demonstrate for the first time an efficient, photonic-based astronomical spectrograph on the 8-m Subaru Telescope. An extreme adaptive optics system is combined with pupil apodi…
Efficient injection from large telescopes into single-mode fibres: Enabling the era of ultra-precision astronomy
N. Jovanovic, C. Schwab, O. Guyon +9
Photonic technologies offer numerous advantages for astronomical instruments such as spectrographs and interferometers owing to their small footprints and diverse range of function…
Data Reduction Pipeline for the CHARIS Integral-Field Spectrograph I: Detector Readout Calibration and Data Cube Extraction
Timothy D. Brandt, Maxime Rizzo, Tyler Groff +14
We present the data reduction pipeline for CHARIS, a high-contrast integral-field spectrograph for the Subaru Telescope. The pipeline constructs a ramp from the raw reads using the…
Visible camera cryostat design and performance for the SuMIRe Prime Focus Spectrograph (PFS)
Stephen A. Smee, James E. Gunn, Mirek Golebiowski +13
We describe the design and performance of the SuMIRe Prime Focus Spectrograph (PFS) visible camera cryostats. SuMIRe PFS is a massively multi-plexed ground-based spectrograph consi…
