Equilibrium model constraints on baryon cycling across cosmic time

The Cosmic Baryon Budget

We present an estimate of the global budget of baryons in all states, with conservative estimates of the uncertainties, based on all relevant information we have been able to marshal. Most of the baryons today are still in the form of ionized gas, which contributes a mean density uncertain by a factor of about four. Stars and their remnants are a relatively minor component, comprising for our b...

Cosmic Matter Distribution: Cosmic Baryon Budget Revisited

The cosmic baryon budget is revisited using modern observations that have become available since our first publication. I also present an estimate for the heavy element abundance. An increased accuracy in the accounting of the baryon budget reveals ‘missing baryons’, which amount to ≈ 35% of the total. This would provide an interesting test for models of the cosmic structure formation.
