Liger: Next Generation Imager and Spectrograph for Keck Observatory Adaptive Optics
·
Abstract
We discuss a next-generation adaptive optics-fed integral field spectrograph and imaging camera for Keck Observatory, known as Liger. Liger will enable new science by offering higher spectral resolution (R∼8000-10000), access to shorter wavelengths (0.84 - 2.4 μm), and larger fields of view than any current and future ground- and space-based IFS.
