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.

  1. High-Energy Neutrinos from Black Hole Evaporation in Neutron Stars

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Repeated collapse of asymmetric dark matter inside neutron stars into evaporating microscopic black holes can produce a Galactic-Center-concentrated high-energy neutrino flux at the 10^-12 GeV cm^-2 s^-1 level, subdom...

  2. Search for GeV-scale Dark Matter from the Galactic Center with IceCube-DeepCore

    astro-ph.HE 2025-11 conditional novelty 6.0 of 10

    Using 9.28 years of IceCube-DeepCore data, no dark-matter neutrino signal is found from the Galactic Center, setting the strongest neutrino-telescope limits for GeV-scale annihilation and decay.

  3. Complementary Planetary Spectroscopy Probes of Dark Matter

    hep-ph 2025-08 conditional novelty 6.0 of 10

    Dark matter annihilation energy deposited in planetary atmospheres and interiors, compared against existing UV airglow and heat flow measurements, yields new sub-GeV scattering constraints and long-lived mediator reach.
