About

Rich Nyquist is a leading innovator in astronomical instrumentation, with a primary focus on high-resolution infrared spectroscopy. His most notable contribution is the development and application of silicon immersion gratings (SIGs), a transformative technology that dramatically enhances the performance of spectrographs. Nyquist’s seminal 2012 paper on the subject demonstrates that SIGs offer a 3.4 times gain in dispersion or a roughly tenfold reduction in instrument volume compared to conventional echelle gratings, while also providing a multiplex advantage for broad wavelength coverage. This breakthrough enables the construction of more compact, powerful instruments for studying exoplanet atmospheres, stellar physics, and galactic dynamics. With 8 citations, this foundational work has established Nyquist as a key figure in the field, paving the way for next-generation telescopes and spectrographs that demand extreme resolution and sensitivity in the infrared. His research continues to shape the future of ground- and space-based astronomical observation.
