The Design of The CCAT-prime Epoch of Reionization Spectrometer Instrument

Understand

The Epoch of Reionization Spectrometer (EoR-Spec) is an instrument module for the Prime-Cam receiver of the 6 m aperture CCAT-prime Telescope at 5600 m in Chile.

• EoR-Spec will perform 158 $\mu$m [CII] line intensity mapping of star-forming regions at redshifts between 3.5 and 8 (420 - 210 GHz), tracing the evolution of structure during early galaxy formation.
• At lower redshifts, EoR-Spec will observe galaxies near the period of peak star formation - when most stars in today's universe were formed.
• At higher redshifts, EoR-Spec will trace the late stages of reionization, the early stages of galaxy assembly, and the formation of large-scale, three-dimensional clustering of star-forming galaxies.
