Abstract
TIME, the Tomographic Ionized Carbon Intensity Mapping Experiment, seeks to probe the structure and evolution of the universe by using line intensity mapping to measure carbon monoxide (CO) and ionized carbon ([CII]) with a mm-wavelength grating spectrometer. The measurements of [CII] will probe matter at redshift 5-9 furthering our understanding of reionization and star formation at these early epochs, while the measurements of CO will probe molecular gas from redshift 1-2.  TIME was installed at the Arizona Radio Observatory 12 m telescope in 2019 and returned for further engineering, commissioning, and observing in January 2022. This talk will summarize the technical specifications of the instrument including detector count, spectral coverage and resolution, and will give an update on the current status of the project. We will discuss measurements taken during the 2022 season and discuss the most recent characterization of the transition edge sensors used for TIME.
