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 […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Wayne Hu, , , , | Summary: Upcoming weak lensing surveys on wide fields will provide the opportunity to reconstruct the structure along the line of sight tomographically by employing photometric redshift information about the source distribution. We define power-spectrum statistics, including cross correlation between redshift bins, […]
Kavli Affiliate: Emil Martinec | First 5 Authors: Miao Li, Emil Martinec, Vatche Sahakian, , | Summary: Making combined use of the Matrix and Maldacena conjectures, the relation between various thermodynamic transitions in super Yang-Mills (SYM) and supergravity is clarified. The thermodynamic phase diagram of an object in DLCQ M-theory in four and five non-compact […]
Kavli Affiliate: Juan I. Collar | First 5 Authors: Juan I. Collar, , , , | Summary: The case for a stable population of solar-bound Earth-crossing Weakly Interacting Massive Particles (WIMPs) is reviewed. A practical general expression for their speed distribution in the laboratory frame is derived under basic assumptions. If such a population exists […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I demonstrate by means of high resolution cosmological simulations, which include modelling of a two-phase interstellar medium, that the dominant mechanism for transporting heavy elements from the proto-galaxies into the IGM is the merger mechanism as discovered by Gnedin […]
