On The Dark Side of Quasar Evolution

Recent improved determinations of the mass density ρBH of supermassive black holes (SMBHs) in the local universe have allowed accurate comparisons of ρBH with the amount of light received from past quasar activity. These comparisons support the notion that local SMBHs are “dead quasars” and yield a value ǫ ∼> 0.1 for the average radiative efficiency of cosmic SMBH accretion. BH coalescences may...

The dark side of cosmology: dark matter and dark energy.

A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of "dark...
