Line intensity mapping (LIM), in which line emission from unresolved galaxies is mapped onto a 3D field, has emerged as a unique probe of the gas content and star formation history of the Universe as well as large-scale structure across cosmic time. In this talk, I will present the science potential of LIM as well as surveys which will provide the data for these analyses. After a brief introduction to LIM, I will introduce the [CII] emission line and explain what mapping this line can teach us about star formation and the interstellar medium, after which I’ll present recent measurements we performed of the diffuse [CII] intensity. Next, I will describe the LIM survey EXCLAIM, a NASA mission which will map CO and [CII] emission to probe star formation and the ISM over cosmic time. Finally, I will present SPHEREx, another upcoming NASA mission which will characterize cosmic inflation as well as the ISM.More details: https://www.simonsfoundation.org/event/cca-colloquium-anthony-pullen/Uploaded 23-10-19
