High Redshift Cluster Abundance

Michael Mortonson, Wayne Hu, & Dragan Huterer

Driver and fitting routines for computing the predicted number of clusters in a ΛCDM cosmology that agrees with CMB, SN, BAO, H0 measurements (up to 2010) at some specified parameter confidence and the mass which would rule out that cosmology at some specified sample confidence.

Code:

Inputs:

Outputs:

Outputs are provided for ΛCDM parameters found by analyzing supernovae (SN) with MCLS2k2 and with SALT2. MCLS2k2 gives higher predicted abundances and more conservative exclusion levels. SALT gives a better global fit to ΛCDM models.
