Detailed Description

NCDM with a grey-body phase-space distribution: f0(q) = 2/(2π)³ (q/q0)^(α-1) / (exp(α x q) + 1). Parameterized directly by (alpha, q0, x) or by inverting velocity moments (r, M2, M3). All perturbation/background behavior is inherited from NCDMSpecies.

GetParam()

std::optional< double > GreyBodyNCDMSpecies::GetParam ( const std::string &  ) const

overridevirtual

Generic species-param accessor for the Python wrapper layer and cross-module readers that don't want to downcast. Each species may opt in by overriding this and returning the named param; default is std::nullopt.

Reimplemented from BaseSpecies.

EvaluatePsdAnalytic()

double GreyBodyNCDMSpecies::EvaluatePsdAnalytic ( double  q ) const

overrideprotectedvirtual

Analytic PSD f0(q) for the non-file case. Base: Fermi-Dirac with chemical potential ksi_. GreyBodyNCDMSpecies overrides this.

Reimplemented from NCDMBaseSpecies.

DefaultQuadratureStrategy()

quadrature_method GreyBodyNCDMSpecies::DefaultQuadratureStrategy ( ) const

overrideprotectedvirtual

Default quadrature strategy when the user leaves quadrature_strategy_ at qm_auto. Base: qm_auto (unchanged). GreyBodyNCDMSpecies returns a GB-specific method. Wired into InitQuadrature in Task 5.1; not consulted yet.

Reimplemented from NCDMBaseSpecies.

FillQuadratureParams()

void GreyBodyNCDMSpecies::FillQuadratureParams ( GBQuadParams &  ) const

overrideprotectedvirtual

Populate grey-body quadrature parameters. Base: leaves p.active == false.

Reimplemented from NCDMBaseSpecies.
