Explore CO and [C II] line-intensity mapping techniques and their role in advancing our understanding of the star-forming cosmic web in this 43-minute conference talk by Dongwoo Chung from Cornell University. Delivered at the New Synergies in Multi-Probe Cosmology conference hosted by the Kavli Institute for Theoretical Physics at UC Santa Barbara, this presentation examines innovative approaches to mapping cosmic structures through spectral line observations. Learn about the latest developments in using carbon monoxide and ionized carbon emission lines as tracers of large-scale structure formation and star formation processes across cosmic time. Discover how these line-intensity mapping methods contribute to multi-probe cosmological studies and cross-correlation analyses with other observational techniques including cosmic microwave background measurements, galaxy surveys, and gravitational lensing data. Gain insights into the technical challenges and opportunities in combining multiple astronomical probes to enhance our understanding of astrophysics and cosmology, particularly in the context of ongoing and future large-scale surveys spanning radio, microwave, optical, and X-ray wavelengths.
