The outer caustics are topological spheres whereas the inner caustics are rings. The self-similar model of galactic halo formation predicts that the caustic ring radii .. follow the approximate la

We describe here an analysis [.] of ground-based proper motion surveys in which nearby dark halo white dwarfs might be present, if they have the colours and absolute magnitudes proposed. Very few such objects have been found, whereas we argue here

Simulations show that the cluster baryon fraction depends on radius and that the present measurements are biased in different ways depending on the radius to which they are calculated. A present limitation is that few clusters have accurate radial tem

In a study of 42 of these supernovae and comparison with 18 “near by” supernovae we have obtained evidence that at the present epoch the expansion of the universe is accelerating. This implies the presence of a positive cosmolog

The actual tiny value of the cosmological constant by particle physics standards represents, therefore, one of the deepest mysteries of present-day fundamental physics. Recent proposals of an approach to the cosmological const
