Gravitational Microlensing of the Galactic Centre -Ray Excess: A New Test for Point-Like or Extended Emission?
Nada Salama, Florian List, Geraint Lewis
We present a potential test of the origin of the -ray Galactic Centre Excess (GCE). We demonstrate how gravitational microlensing by stellar mass objects along the line of sigh…
