Description
More than 10 years ago, an excess of $\gamma$-ray photons coming from the Galactic center was discovered in the Fermi-LAT data. First attributed to dark matter, it has since been shown that it should have at least a partial stellar origin. One intereseting explanation to the excess is the presence of a population of millisecond pulsars (MSPs) confined in the Galactic bulge. While unresolved in $\gamma$-rays, Berteaud et al. (2021) showed that some of these MSPs could already have been detected in past observations from the Chandra X-ray observatory and selected promising MSP candidates among unidentified Chandra-detected sources. In this poster, I will present our recent progresses in the selection of MSP candidates, unveiling compact objects and promising sources with X-ray and radio emission only. Our project motivated and obtained deep targeted radio observations which are essential for the identification of pulsars in the Galactic bulge.
