Evidence for some hot dark matter?
Article Abstract:
The cold plus hot dark matter (CPHDM) model has received strong confirmation from the cosmic background explorer satellite and from observations of the Universe's inflationary structure. Astrophysicists have long argued the relative merits of the cold dark matter model versus the hot dark matter model. However, the preponderance of evidence shows that the Universe is flat with a fraction of its critical energy density in massive relic neutrinos. These observations bear out the CPHDM model.

The physics of microwave background anisotropies
Article Abstract:
Analysis of the physical mechanisms of anisotropies in the cosmic microwave background (CMB) could provide valuable information on the origin of large-scale structure in the universe. CMB anisotropies, or small variations in its temperature across the sky, result from simple linear processing of the primordial fluctuations through gravitational and particle interactions. Observations of the anisotropy also provide insight into the origin of perturbations in the early universe.

Big Bang brouhaha: caution in celebrating last week's announcement of anisotropies in the microwave background would be wise
Article Abstract:
The COBE microwave satellite's detection of anisotropies in the microwave background radiation has led the press to trumpet the premature conclusion that the Big Bang theory has been proven. Although the new data strongly support the Big Bang model of the universe's origin and structure, to interpret the results as definitive proof is unwarranted. The data must be more extensively analysed before its status as evidence for or against the Big Bang can be properly determined.
