Abstract

We will present the status of the next generation near-infrared (0.84 - 2.45 micron) imager and integral field spectrograph (IFS) instrument, Liger, that is being designed for the W. M. Keck Observatory. The Liger imager and IFS operates concurrently on-sky and are optimized to sample the Keck All-sky Precision Adaptive optics (KAPA) system. The Liger IFS design is able to offer new science capabilities by extending to bluer wavelength coverage, larger field of views, and range of spectral resolving powers. We will discuss the overall Liger technical design, science requirements, and implementation plans for the entire program.
