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: Edmund Bertschinger | First 5 Authors: Hale Bradt, Ronald A. Remillard, , , | Summary: A concept for an all-sky monitor mission substantially more powerful than the RXTE ASM is presented in brief. It makes use of 31 Gas Electron Multiplier (GEM) proportional counters to provide continuous monitoring of the entire x-ray sky, […]
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, […]
