Intensity mapping with CO(1-0) and CII as probes of primordial non-Gaussianity

15.03.2019 11:30 – 12:30

Primordial non-Gaussianity is a unique window into the physics of the early universe and the origin of primordial fluctuations. I will present some of our recent work on exploring the potential of future CO and CII intensity mapping surveys in constraining primordial non-Gaussianity, via power spectrum measurement. I will discuss the characteristics of optimal survey designs that can achieve the target sensitivity of sigma(fnl) = 1, as well as the impact of modeling uncertainties on the obtained constraints. I will also discuss some of the prospects of multi-tracer analysis in improving the constraints.
