About
Kyle B. Westfall is an astronomer and instrumentation specialist whose work centers on the design and development of cutting-edge multi-object spectrographs for next-generation telescopes. His primary research areas include astronomical instrumentation, optical spectroscopy, and the engineering of high-resolution spectrographs for ground-based observatories. Westfall’s most notable contribution is his leadership in the instrument trade study for the Wide Field Optical Spectrometer (WFOS), a first-light instrument for the Thirty Meter Telescope (TMT). His 2018 paper, "WFOS instrument trade study: slicer vs. fiber instrument concept designs and results," which has garnered 7 citations, presents a critical comparison of two competing optical designs—image slicers versus fiber-fed systems—to optimize WFOS’s performance. This work directly informed the final instrument architecture, ensuring that WFOS will deliver a minimum spectral resolution of R~5,000 across a simultaneous 31-wavelength range when TMT begins observations in 2027. Westfall’s meticulous analysis of trade-offs in throughput, spatial resolution, and mechanical complexity has made him a key figure in the TMT project, bridging the gap between scientific requirements and practical engineering constraints. His contributions are vital to enabling transformative discoveries in galaxy evolution, star formation, and cosmology.
