halomod.halo_exclusion.NoExclusion¶

class halomod.halo_exclusion.NoExclusion(m: ndarray, density: ndarray, power_integrand: ndarray, bias: ndarray, r: ndarray, halo_density: float)[source]¶

Bases: Exclusion

A model where there’s no halo exclusion.

density_mod¶

The modified integrated density with halo exclusion.

Calculated in the matter case by

\[\bar{n}^{-1} \sqrt{\int_0^{m'_1} \int_0^{m'_2} n(m_1) m_1 n(m_2) m_2 dm_1 dm_2},\]

and in the tracer case by replacing n(m).m with n(m) N(m).

See Eq. 47 of https://arxiv.org/pdf/2009.14066.

The array is a vector of length r.

classmethod get_models() → Dict[str, Type]¶: Get a dictionary of all implemented models for this component.

integrate() → ndarray[source]¶

Integrate the raw_integrand() over mass.

Returns:: An array of shape (r, k) that should be multiplied by P_m(k) to obtain the 2-halo power spectrum.
Return type:: np.ndarray

property r_halo¶: The virial radius of the halo.

raw_integrand() → ndarray¶

Compute the full power spectrum integrand.

The output is always a 3D array, with shape (r, k, m).
