Bio
I am a postdoctoral scholar at the National Institute for Subatomic Physics (Nikhef) and Utrecht University, in the Netherlands. My research interests include the detection of gravitational waves from neutron stars, primordial black holes binaries and particle dark matter. I am a member of the LIGO-Virgo-KAGRA collaborations.
Description
Over ten years ago, Fermi observed an excess of GeV gamma rays from the Galactic Center whose origin is still under debate. One explanation for this excess involves annihilating dark matter; another requires an unresolved population of millisecond pulsars concentrated at the Galactic Center. We have shown in our recent paper that gravitational waves could be used as a way of constraining the origins of this excess. In this project, we will explore how these constraints vary when choosing assuming different distributions of neutron-star frequency and deformation size, and use derived distributions from recent works to place new constraints on the GeV excess.
