ISW-Correlation
This code is based on a modified version of CMBFAST 4.5.1 by U. Seljak & M. Zaldarriaga which computes the ISW-correlation power spectrum for a given cosmological model and a galaxy selection function. It includes perturbation equation of a generic dark energy fluid with constant or linearly evolving equation of state and constant sound speed.
Dark Matter Halo Sparsity
This code computes the average halo sparsity for massive halos (>1013 MSun h-1) at a given redshift for a given cosmological model by solving Eq. (4) in Corasaniti et al. (2018) for two different overdensity cases (\(\langle s_{200,500}\rangle\) and \(\langle s_{500,1000}\rangle\)) assuming the mass function parametrizations from Despali et al. (2016) or calibrated against the RayGal simulation halo catalogs. In the case of the Despali et al. (2016) mass function the average sparsity includes the matched halo correction calibrated on the RayGal simulations.
