The Tomographic Ionized Carbon Intensity Mapping Experiment is a mm-wavelength spectrometer we are building at Caltech to study the epoch of reionization (EoR). The instrument is a 200-300 GHz spectrometer with resolving power, R, of ~ 100.
The technique we are pursuing by building the TIME instrument, ionized carbon ([CII]) intensity mapping, is a promising approach to study the EoR, and recent instrumentation advances are enabling strides forward with these measurements. These ionized carbon ([CII]) intensity mapping measurements of faint galaxies will be highly complementary to the 21 cm measurements as well as complimentary to the measurements of the galaxies at the bright end of the luminosity function with ALMA, HST, and JWST. Together these cutting-edge instruments will start to create a picture of this largely unexplored epoch.
