Neutrinos from captured dark matter annihilation in a galactic population of neutron stars

Understand

Particulate dark matter captured by a population of neutron stars distributed around the galactic center while annihilating through long-lived mediators can give rise to an observable neutrino flux.

• We examine the prospect of an idealised gigaton detector like IceCube/KM3NeT in probing such scenarios.
• Within this framework, we report an improved reach in spin-dependent and spin-independent dark matter nucleon cross-section below the current limits for dark matter masses in the TeV-PeV range.
