Statistical treatment of searches for counterparts of positionally-uncertain astrophysical sources: from flux upper limits to detection
Julian Sitarek, Abelardo Moralejo, Juan Jiménez Quiles +3
The paper compares frequentist, Bayesian, and agnostic statistical methods for analyzing follow‑up observations of poorly localized astrophysical alerts, such as gravitational‑wave…

On the Blueprint of Active Galaxies Producing Neutrinos
Chen Li, Francis Halzen
The paper argues that high‑energy neutrinos observed from certain active galaxies are generated within a few gravitational radii of their supermassive black holes, where accelerate…

A self-consistent Higgs-portal framework for dark matter--admixed neutron stars: Collider-motivated benchmarks meet multimessenger constraints
Adamu Issifu
The paper develops a self-consistent relativistic mean‑field model that couples baryonic matter and dark matter in neutron stars via a Higgs‑portal with a massive Z′ vector mediato…
