Favored Variants of Cold Dark Matter Cosmologies

Rachel S. Somerville, Joel R. Primack

We discuss variants of Cold Dark Matter (CDM) dominated cosmological models that give good agreement with a range of observations. We consider models with hot dark matter, tilt, $Ω…

Cosmological Structure Formation With and Without Hot Dark Matter

Joel Primack

Cold + Hot Dark Matter (CHDM) is perhaps the best theory of cosmic structure formation {\it if} the cosmological matter density is near critical (i.e., $Ω_{0} \approx 1$ ) and {\it if…

Status of Cosmological Parameters: $Ω_{0} \approx 0.3$ vs. $Ω = 1$

Joel R. Primack

The cosmological parameters that I discuss are the Hubble parameter $H_{0} \equiv 100 h$ km s $^{- 1}$ Mpc $^{- 1}$ , the age of the universe $t_{0}$ , the average density $Ω_{0}$ , and the cos…
