Superstring cosmology
Aspects of superstring cosmology are reviewed with an emphasis on the cosmological
implications of duality symmetries in the theory. The string effective actions are summarized …

Relativistic cosmology and large-scale structure
General relativity marked the beginning of modern cosmology and it has since been at the
centre of many of the key developments in this field. In the present review, we discuss the …

Larger values in the CMB dipole direction
Based on the assumption that quasars (QSOs) and gamma-ray bursts (GRBs) represent
standardizable candles, we provide evidence that the Hubble constant H 0 adopts larger …

Covariant and gauge-invariant approach to cosmological density fluctuations
It has been known for a long time that the gauge problem plagues the study of density
perturbations in cosmology. The quantity δμ/μ (the fractional variation in density along a …

Kinematical conditions in the construction of spacetime
L Smarr, JW York Jr - Physical Review D, 1978 - APS
We adopt the point of view that a solution of Einstein's equations is an evolution of given
initial Cauchy data. Implementing the evolution equations necessarily requires a …

Cosmological perturbations and the physical meaning of gauge-invariant variables
In this paper we compare the covariant and gauge-invariant (GI) approach of Ellis and Bruni
(1989)(EB) with the coordinate-based approach of Bardeen (1980)(BI). To do this we …
