We present a model for cold dark matter based upon continuum bound states of thee + e − system. These continuum bound states, referred to as photonium states to distinguish them from the well-known bound states of positronium, are shown to have cross sections and lifetime properties consistent with abundant production in the early universe and survival

The Cold + Hot Dark Matter (CHDM) model appears to require about 5 eV of neutrino mass in order to produce early enough galaxy formation. Recent experimental data suggests that this neutrino mass may be divided between two species of neutrinos, each with mass of about 2.4 eV.

The successful cold dark matter (CDM) theory for the formation of structure in the Universe has suffered recent setbacks from observational evidence suggesting that there is more large-scale structure than it can explain. This may force a fundamental revision or even abandonment of the theory, or may simply reflect a modulation of the galaxy ...

The nature of dark matter is increasingly constrained by cosmological data. In this paper, we examine the implications of the cosmic microwave background anisotropy limits on the density of cold dark matter under different theoretical assumptions and combinations of data sets.
