Why a Windy Torus?
S. C. Gallagher, M. M. Abado, J. E. Everett +2
Mass ejection in the form of winds or jets appears to be as fundamental to quasar activity as accretion, and can be directly observed in many objects with broadened and blue-shifte…
The WiggleZ Dark Energy Survey: measuring the cosmic growth rate with the two-point galaxy correlation function
Carlos Contreras, Chris Blake, Gregory B. Poole +24
The growth history of large-scale structure in the Universe is a powerful probe of the cosmological model, including the nature of dark energy. We study the growth rate of cosmic s…
The structure of the merging RCS 231953+00 Supercluster at z ~ 0.9
A. J. Faloon, T. M. A. Webb, E. Ellingson +8
The RCS 2319+00 supercluster is a massive supercluster at z=0.9 comprising three optically selected, spectroscopically confirmed clusters separated by <3 Mpc on the plane of the sk…
Super-luminous supernovae at redshifts of 2.05 and 3.90
Jeff Cooke, Mark Sullivan, Avishay Gal-Yam +6
A rare class of `super-luminous' supernovae that are about ten or more times more luminous at their peaks than other types of luminous supernovae has recently been found at low to…
Simulating Cosmic Reionization and the Radiation Backgrounds from the Epoch of Reionization
Paul R. Shapiro, Ilian T. Iliev, Garrelt Mellema +10
Large-scale reionization simulations are described which combine the results of cosmological N-body simulations that model the evolving density and velocity fields and identify the…
Non-Gaussianity from Axionic Curvaton
Masahiro Kawasaki, Takeshi Kobayashi, Fuminobu Takahashi
We study non-Gaussianity of density perturbations generated by an axionic curvaton, focusing on the case that the curvaton sits near the hilltop of the potential during inflation.…
