Project C6

Project leaders: Porciani, Cristiano (AIfA); Riechers, Dominik (PH1)

If a line intensity mapping (LIM) measurement is made, what can we infer about the properties and spatial distribution of the underlying population of emitters? The main objective of sub-project C6 is to answer this question by (i) building estimators for different summary statistics that can be extracted from the maps; (ii) generating realistic mock data sets on which to test the estimators; (iii) building a Bayesian toolkit to reconstruct key properties of the underlying galaxy population from the measured data. Direct applications of our findings to the line intensity maps obtained with FYST in sub-project C3 are an integral part of the research done in C6.
