MIT Astrophysics Colloquium 09/19/2023 — Abigail Crites: Probing The Structure And Evolution Of Our Universe

Tuesday September 19, 2023 4:00 pm

Title: Probing the Structure and Evolution of Our Universe with Line Intensity Mapping and mm-Wavelength Instruments 

Abstract: I will discuss line intensity mapping (LIM) and its applications for understanding cosmology and star-formation across cosmic time. I will focus on TIME, a mm-wavelength instrument designed to use LIM to probe the [CII] line at redshifts ~5-9 and the CO lines at redshifts ~0.5-2. The instrument is a grating spectrometer with transition edge sensors that is used on the Arizona Radio Observatory 12m. I will also briefly touch on other instruments and facilities (including the Fred Young Submilimeter Telescope) that will be used for LIM and the future of cosmology using this technique.
