Abstract: The non-Gaussianity of the initial conditions leaves its imprints on the large scale structure. While the upcoming galaxy surveys will provide data with an unprecedented volume and precision, a novel observational technique referred to as line intensity mapping is also attracting significant amount of attention, given its unique potential to probe the universe at the range of scales and redshifts not accessible to galaxy surveys. In this talk, I will discuss a few different aspects of using these two observational windows to constrain primordial non-Gaussianity. In particular, I’ll discuss (a) the prospects of intensity mapping with CO and [CII] emission lines and its synergies with galaxy surveys, (b) the impact of modes larger than the size of a given survey on the measurement of clustering statistics within the survey, (c) the optimal estimators to extract information from clustering bispectrum.
