Kavli Affiliate: Robert Rosner | First 5 Authors: Alexandros Alexakis, Yuan-Nan Young, Robert Rosner, , | Summary: We study the weakly non-linear development of shear-driven gravity waves, and investigate the mixing properties of the finite amplitude solutions. Calculations to date have been restricted to the linear theory, which predicts that gravity waves are amplified by […]
Kavli Affiliate: Wendy Freedman | First 5 Authors: Wendy L. Freedman, , , , | Summary: New, large, ground and space telescopes are contributing to an exciting and rapid period of growth in observational cosmology. The subject is now far from its earlier days of being data-starved and unconstrained, and new data are fueling a […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Jonathan L. Rosner, , , , | Summary: An elementary description of CP violation for the non-specialist is presented. This article, for publication in {it Macmillan Encylopedia of Physics, Supplement: Elementary Particle Physics}, is being submitted to the Archive for comments by colleagues. | Search Query: […]
Kavli Affiliate: Emil Martinec | First 5 Authors: Emil Martinec, Will McElgin, , , | Summary: We consider worldsheet string theory on $Z_N$ orbifolds of $AdS_3$ associated with conical singularities. If the orbifold action includes a similar twist of $S^3$, supersymmetry is preserved, and there is a moduli space of vacua arising from blowup modes […]
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 […]
