Towards understanding interactions between the AO system and segment co-phasing with the vector-Zernike wavefront sensor on Keck
Maïssa Salama, Charlotte Guthery, Vincent Chambouleyron +14
We extend our previous demonstration of the first on-sky primary mirror segment closed-loop control on Keck using a vector-Zernike wavefront sensor (vZWFS), which improved the Stre…
Reference star differential imaging of close-in companions and circumstellar disks with the NIRC2 vortex coronagraph at W.M. Keck Observatory
Garreth Ruane, Henry Ngo, Dimitri Mawet +11
Reference star differential imaging (RDI) is a powerful strategy for high contrast imaging. Using example observations taken with the vortex coronagraph mode of Keck/NIRC2 in $L^\p…
Lessons for WFIRST CGI from ground-based high-contrast systems
Vanessa P. Bailey, Michael Bottom, Eric Cady +26
The Coronagraph Instrument (CGI) for NASA's Wide Field Infrared Survey Telescope (WFIRST) will constitute a dramatic step forward for high-contrast imaging, integral field spectros…
Characterizing the performance of the NIRC2 vortex coronagraph at W.M. Keck Observatory
W. Jerry Xuan, Dimitri Mawet, Henry Ngo +15
The NIRC2 vortex coronagraph is an instrument on Keck II designed to directly image exoplanets and circumstellar disks at mid-infrared bands (3.4-4.1 m) and (4.…
Observing Exoplanets with High-Dispersion Coronagraphy. II. Demonstration of an Active Single-Mode Fiber Injection Unit
Dimitri Mawet, Garreth Ruane, Wenhao Xuan +12
High-dispersion coronagraphy (HDC) optimally combines high contrast imaging techniques such as adaptive optics/wavefront control plus coronagraphy to high spectral resolution spect…
