zreion 0.2.2

A python-based method for generating cosmological reionization fields

zreion

zreion is a way of quickly computing a "redshift of reionization" field using a semi-numeric method developed in Battaglia et al. (2013). The method assumes the redshift of reionization for a particular point in a cosmological volume is a biased tracer of the matter field, and can be written as a parameterized bias function. For a full derivation and comparison with simulations, see the linked paper.
