Description
The Galactic-Center Excess, a surplus of gamma rays at the Milky Way’s core, has sparked debate
over its origins, with two main theories suggesting either dark matter annihilation or emissions from mil-
lisecond pulsars as potential sources. This study utilizes data from the Laser Interferometer Gravitational-
Wave Observatory (LIGO) to explore the presence of millisecond pulsars in the galactic center. Employ-
ing PyFstat, an MCMC tool optimized for continuous gravitational wave detection, we analyzed gravi-
tational wave signals emitted by millisecond pulsars, revealing significant insights into their distribution
and activities. Our findings suggest that expanding the search aperture in future LIGO observation runs
could enhance the detection of these pulsars, contributing to a better understanding of the Galactic-Center
Excess and the nature of energetic processes within our galaxy’s nucleus.
