After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

The formation of the first stars and quasars marks the transformation of the universe from its
smooth initial state to its clumpy current state. In popular cosmological models, the first …

We present the large-scale correlation function measured from a spectroscopic sample of
46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers …

We measure cosmological parameters using the three-dimensional power spectrum P (k)
from over 200 000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with …

We present here the final results of the Hubble Space Telescope (HST) Key Project to
measure the Hubble constant. We summarize our method, the results, and the uncertainties …

We recently introduced the concept of “k-essence” as a dynamical solution for explaining
naturally why the universe has entered an epoch of accelerated expansion at a late stage of …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

We introduce a new cosmological diagnostic pair {r, s} called the Statefinder. The Statefinder
is a geometrical diagnostic and allows us to characterize the properties of dark energy in a …

The scalar-tensor theory of gravitation is one of the most popular alternatives to Einstein's
theory of gravitation. This book provides a clear and concise introduction to the theoretical …

It may be possible to construct a laser interferometer gravitational wave antenna in space
with h rms∼ 10− 27 at f∼ 0.1 Hz in this century. Using this antenna,(1) typically 10 5 chirp …
