DMHaloModel.power_hh(k, mmin=None, mmax=None, mmin2=None, mmax2=None)[source]

The halo-centre power spectrum of haloes in a given mass range.

The power of a given pair of halo masses is assumed to be linearly biased, \(P_hh(k) = b(m_1)b(m_2)P_{lin}(k)\)

Parameters

  • k (np.ndarray) – Array of wavenumbers. Units h/Mpc.

  • mmin (real, default Mmin) – The minimum halo mass of the range (for the first of the halo pairs). Note: masses here are log10 masses.

  • mmax (real, default None) – The maximum halo mass of the range (for the first of the halo pairs). If a single halo mass is desired, set mmax==mmin.

  • mmin2 (real, default None) – The minimum halo mass of the range (for the second of the halo pairs). By default, takes the same value as mmin.

  • mmax – The maximum halo mass of the range (for the second of the halo pairs). By default, takes the same value as mmax.
