PBHtest
PBHtest is a proposed diagnostic framework in astrophysics and cosmology designed to assess evidence for primordial black holes (PBHs) in observational data. The goal is to evaluate PBH dark matter hypotheses and PBH formation scenarios by integrating multiple data streams into a single statistical test. The framework treats PBHs as a population characterized by a mass function, spatial distribution, and possible clustering, and it aims to produce mass- and model-dependent constraints rather than isolated signals.
Core components of PBHtest include: (1) microlensing and femtolensing analyses of stellar and extragalactic sources to
Outputs consist of a mass-dependent PBH abundance constraint, posterior distributions for PBH parameters, and model-viability assessments
Limitations include dependence on priors about the PBH mass spectrum, uncertainties in lensing and accretion physics,
