Abstract
A “catalogue” of x-ray clusters in the cold dark matter (CDM) model is constructed numerically. The x-ray properties of these rare objects are used to constrain the normalization of the CDM spectrum, resulting in a preferred “bias parameter” b = 1.7. The simulated clusters also provide a means of testing the accuracy of observational x-ray mass estimates — the simplest hydrostatic isothermal model is found to underestimate the true mass within Abell radii by a systematic factor of 1.5.
