class CMB : public BlackbodyPhotonField

Cosmic mircowave background photon field.

Source info: This field is an isotropic blackbody photon field with temperature T = 2.73 K

Public Functions

inline CMB()
virtual double getPhotonDensity(double ePhoton, double z = 0.) const

returns comoving photon density [1/m^3]. multiply with (1+z^3) for physical number density.

  • ePhoton – photon energy [J]

  • z – redshift (if redshift dependent, default = 0.)

virtual double getMinimumPhotonEnergy(double z) const
virtual double getMaximumPhotonEnergy(double z) const
void setQuantile(double q)
inline virtual std::string getFieldName() const
inline virtual double getRedshiftScaling(double z) const

returns overall comoving scaling factor (cf. CRPropa3-data/


z – redshift

inline bool hasRedshiftDependence() const
inline void setFieldName(std::string fieldName)
inline size_t addReference() const
inline size_t removeReference() const
inline int removeReferenceNoDelete() const
inline size_t getReferenceCount() const
