Numerical simulations and statistical tools for line intensity mapping (C06)

• Subject Area: Astrophysics and Astronomy
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 500700252

If a line-intensity-mapping measurement is made, what can we infer about the properties and spatial distribution of the underlying population of emitters? The main objective of this project 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 are an integral part of the research done in our project.
