Class structures

source code

This class was contructed based in the like Press-Schechter formalism
that provides characteristis like numerical density of dark matter halos
into the range m_h, m_h + dm_h, the fraction of barionic matter,
and,  the accretion rate of barions into structures and the total number
of dark halos.

The models used to develop this class was presented for the first time
in the article of Pereira and Miranda (2010) - (MNRAS, 401, 1924, 2010).

The cosmologic background model is passed as a instance parameter:
    cosmology

Keyword arguments:
    lmin -- (default 6.0) log10 of the minal mass of the dark halo
                        where it is possible to have star formation.

    zmax -- (defaul 20.0) - the maximum redshift to be considered

    omegam -- (default 0.24) - The dark matter parameter

    omegab -- (default 0.04) - The barionic parameter

    omegal -- (default 0.73) - The dark energy parameter

    h -- (default 0.7) - The h of the Hubble constant (H = h * 100)
