Dimpled scalar vortex coronagraph laboratory demonstration
Niyati Desai, Garreth Ruane, Susan Redmond +3
Achieving the Habitable Worlds Observatory (HWO) goal of 10^-10 contrast at a separation of 3 /D across a 20% bandwidth requires coronagraph focal plane masks with both broadba…
Technical description and performance of the phase II version of the Keck Planet Imager and Characterizer
Nemanja Jovanovic, Daniel Echeverri, Jacques-Robert Delorme +46
The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction limited, high…
Stellar Coronagraphy
Eugene Serabyn, Michael Bottom
Detecting exoplanets and other faint sources of emitted and reflected light near a bright star requires deeply suppressing the starlight while efficiently transmitting the dim ligh…
Validation of millimetre and submillimetre atmospheric collision induced absorption at Chajnantor
J. R. Pardo, C. De Breuck, D. Muders +9
Due to the importance of a reference atmospheric radiative transfer model for both planning and calibrating ground-based observations at millimetre and submillimetre wavelengths, w…
