Visible and Near Infrared Laboratory Demonstration of a Simplified Pyramid Wavefront Sensor
Julien Lozi, Nemanja Jovanovic, Olivier Guyon +4
Wavefront sensing and control are important for enabling one of the key advantages of using large apertures, namely higher angular resolutions. Pyramid wavefront sensors are becomi…
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…
SCExAO/CHARIS Near-IR High-Contrast Imaging and Integral Field Spectroscopy of the HIP 79977 Debris Disk
Sean Goebel, Thayne Currie, Olivier Guyon +13
We present new, near-infrared (1.1--2.4 ) high-contrast imaging of the bright debris disk surrounding HIP 79977 with the Subaru Coronagraphic Extreme Adaptive Optics system (S…
From Lab Testing to Science: Applying SAPHIRA HgCdTe L-APD Detectors to Adaptive Optics
Sean Goebel
Due to their high frame rates, high sensitivity, low noise, and low dark current, SAPHIRA detectors provide new capabilities for astronomical observations. The SAPHIRA detector is…
LASSO: Large Adaptive optics Survey for Substellar Objects using the new SAPHIRA detector on Robo-AO
Maissa Salama, James Ou, Christoph Baranec +13
We report on initial results from the largest infrared AO direct imaging survey searching for wide orbit (>100 AU) massive exoplanets and brown dwarfs as companions around young ne…
Large Adaptive Optics Survey for Substellar Objects (LASSO) Around Young, Nearby, Low-mass Stars with Robo-AO
Maissa Salama, James Ou, Christoph Baranec +16
We present results from the Large Adaptive optics Survey for Substellar Objects (LASSO), where the goal is to directly image new substellar companions (<70 M) at wide orbit…
