Kavli Affiliate: Bradford A. Benson | First 5 Authors: Robert A. Benjamin, Bradford A. Benson, Donald P. Cox, , | Summary: Radiative cooling is an important ingredient in hydrodynamical models involving evolution of high temperature plasmas. Unfortunately, calculating an accurate cooling coefficient generally requires the solution of over a hundred differential equations to follow the […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Daniel E. Holz, Anthony Zee, , , | Summary: As has been previously proposed, a minimal modification of the standard $SU(3)times SU(2)times U(1)$ theory provides a viable dark matter candidate. Such a particle, a scalar gauge singlet, is naturally self-interacting—making it of particular interest given recent developments […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Daniel Cormier, Katrin Heitmann, Anupam Mazumdar, , | Summary: Coupled, multi-field models of inflation can provide several attractive features unavailable in the case of a single inflaton field. These models have a rich dynamical structure resulting from the interaction of the fields and their associated fluctuations. We […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Gilbert P. Holder, John E. Carlstrom, , , | Summary: We investigate the impact of gas evolution on the expected yields from deep Sunyaev-Zel’dovich (SZ) effect surveys as well as on the expected SZ effect contribution to fine scale anisotropy in the Cosmic Microwave Background. The […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Daniel E. Holz, , , , | Summary: With the advent of large, deep surveys, the observation of a strongly gravitationally lensed supernova becomes increasingly likely. High-redshift surveys continue apace, with a handful of type Ia supernovae observed to date at redshifts of one or greater. In […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: J. E. Carlstrom, M. Joy, L. Grego, G. Holder, W. L. Holzapfel | Summary: The Sunyaev-Zel’dovich effect (SZE) provides a powerful tool for cosmological studies. Through recent advances in instrumentation and observational techniques it is now possible to obtain high quality measurements of the effect toward […]
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 […]
