Kavli Affiliate: Katrin Heitmann | First 5 Authors: Katrin Heitmann, , , , | Summary: We study the abelian Higgs model out-of-equilibrium in two different approaches, a gauge invariant formulation, proposed by Boyanovsky et al. cite{Boyanovsky:1996dc} and in the Coulomb gauge. We show that both approaches become equivalent in a consistent one loop approximation. Furthermore, […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Michael D. Gladders, H. K. C. Yee, , , | Summary: The Red-Sequence Cluster Survey (RCS) is a 100 deg$^2$ optical survey for high-redshift galaxy clusters. One of the goals of the survey is a measurement of $Ω_m$ and $σ_8$ via the evolution of the mass spectrum […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael D. Gladders, H. K. C. Yee, , , | Summary: The Red-Sequence Cluster Survey (RCS) is a new galaxy cluster survey designed to provide a large sample of optically selected 0.1$<$z$<$1.4 clusters. The planned survey data are 100 square degrees of two color ($R$ and […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I show how the existing observational data on Local Group dwarf galaxies can be used to estimate the average star formation law during the first 3 Gyr of the history of the universe. I find that the observational […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael D. Gladders, H. K. C. Yee, , , | Summary: Numerous methods for finding clusters at moderate to high redshifts have been proposed in recent years, at wavelengths ranging from radio to X-rays. In this paper we describe a new method for detecting clusters in […]
Kavli Affiliate: Geza Gyuk | First 5 Authors: Evalyn I. Gates, Geza Gyuk, , , | Summary: We suggest a new component of the Milky Way galaxy that can account for both the optical depth and the event durations obtained by the MACHO microlensing survey toward the Large Magellanic Cloud. This component is consistent with […]
Kavli Affiliate: Edward Kolb | First 5 Authors: Edward W. Kolb, , , , | Summary: There is very strong circumstantial evidence that there was an inflationary epoch very early in the history of the universe. In this lecture I will describe how we might be able to piece together some understanding of the dynamics […]
Kavli Affiliate: Emil Martinec | First 5 Authors: Emil Martinec, Vatche Sahakian, , , | Summary: We study the thermodynamics of the D1-D5 system on a five-torus, focussing on the roles of different scales. One can take a decoupling limit such that the tension of the `little string’ inside the fivebrane remains finite and the […]
Kavli Affiliate: Geza Gyuk | First 5 Authors: Geza Gyuk, Arlin Crotts, , , | Summary: We provide a set of microlensing optical depth maps for M31. Optical depths towards Andromeda were calculated on the basis of a four component model of the lens and source populations: disk and bulge sources lensed by bulge, M31 […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Gilbert P. Holder, John E. Carlstrom, , , | Summary: The Sunyaev-Zel’dovich (SZ) effect from clusters of galaxies should yield a significant signal in cosmic microwave background(CMB) experiments at small angular scales ($ell ga 1000$). Experiments with sufficient frequency coverage should be able to remove much […]
