Bias and high-order galaxy correlation functions in the APM Galaxy Survey
E. Gaztanaga, J. Frieman
On large scales, the higher order moments of the mass distribution, $S_J=\xibar_J/\xibar_2^{J-1}$, e.g., the skewness and kurtosis , can be predicted using non-linear pe…
Microwave background anisotropy in low- inflationary models and the scale of homogeneity in the Universe
A. Kashlinsky, I. I. Tkachev, J. Frieman
We study the microwave background anisotropy due to superhorizon-size perturbations (the Grischuk-Zel'dovich effect) in open universes with negative spatial curvature. Using COBE r…
Gravitational Lens Time Delays and Gravitational Waves
J. Frieman, D. Harari, G. Surpi
Using Fermat's principle, we analyze the effects of very long wavelength gravitational waves upon the images of a gravitationally lensed quasar. We show that the lens equation in t…
The Standard Cosmology
Josh Frieman
These lectures provide an introductory review of big bang cosmology. I discuss the expanding Friedmann-Robertson-Walker universe, summarizing the observational evidence which has l…
