Unveil millisecond pulsar populations at the heart of the Milky Way

A large population of millisecond pulsars (MSPs) has been predicted towards the inner regions of our Galaxy, but only very few have been found so far, questioning either our ability to detect them or the existence of such large population. Interpreting the current detections requires a precise modelling of the underlying populations coupled with sensitivity thresholds of the observations performed. The aim of this PhD project is to develop a simulation-based inference statistical framework to constrain the Galactic populations of MSPs, to search for new MSPs using ambitious radio surveys and test the evidence we have for a bulge population. Results obtained and multi-wavelength properties of MSPs found will be compared to predictions from stellar evolution and used to understand the contribution of MSPs to the Fermi GeV excess, with important implications for its dark matter interpretation.
