End-to-end simulations of a near-infrared pyramid sensor on Keck II
Cédric Plantet, Guido Agapito, Christophe Giordano +3
The future upgrade of Keck II telescope's adaptive optics system will include a pyramid wavefront sensor working in the near-infrared (J and H band). It will benefit from the recen…
Ground Layer Adaptive Optics for the W. M. Keck Observatory: Feasibility Study
J. R. Lu, M. Chun, S. M. Ammons +12
Ground-layer adaptive optics (GLAO) systems offer the possibility of improving the "seeing" of large ground-based telescopes and increasing the efficiency and sensitivity of observ…
Three years of harvest with the vector vortex coronagraph in the thermal infrared
Olivier Absil, Dimitri Mawet, Mikael Karlsson +25
For several years, we have been developing vortex phase masks based on sub-wavelength gratings, known as Annular Groove Phase Masks. Etched onto diamond substrates, these AGPMs are…
Observations of DG Tauri with the Keck Interferometer
M. Colavita, R. Akeson, P. Wizinowich +1
We present the first science results from the Keck Interferometer, a direct-detection infrared interferometer utilizing the two 10-meter Keck telescopes. The instrument and system…
