This paper summarizes the physical mechanisms that encode the type and quantity of cosmological matter in the properties of large-scale structure, and reviews the application of such tests to current datasets. The key lengths of the horizon size at matter-radiation equality and at last scattering determine the total matter density and its ratio to the relativistic density; acoustic oscillations can diagnose whether the matter is collisionless, and small-scale structure or its absence can limit…

4 Observational Cosmology
I discuss the classical cosmological tests– angular size-redshift, flux-redshift, and galaxy number counts– in the light of the cosmology prescribed by the interpretation of the CMB anisotropies. The
Long-lived quintessential scalar hair

• 2006
We investigate static configurations of a vacuumless scalar field as ‘hair’ on a black hole. The vacuumless field has run-away behaviour, meaning the scalar potential vanishes only at infinite field
Torsion, Scalar Field, Mass and FRW Cosmology
In the Einstein–Cartan space U4, an axial vector torsion together with a scalar field connected to a local scale factor have been considered. By combining two particular terms from the SO(4, 1)
