Scale Dependence of Halo Bispectrum from Non-Gaussian Initial Conditions in Cosmological N-body Simulations [PDF]
, 2010 We study the halo bispectrum from non-Gaussian initial conditions. Based on a set of large $N$-body simulations starting from initial density fields with local type non-Gaussianity, we find that the halo bispectrum exhibits a strong dependence on the ...

Halo properties and secular evolution in barred galaxies
, 2005 The halo plays a crucial role in the evolution of barred galaxies. Its near-resonant material absorbs angular momentum emitted from some of the disc particles and helps the bar become stronger.

Self-consistent massive disks in triaxial dark matter halos [PDF]
, 2007 Galactic disks in triaxial dark matter halos become deformed by the elliptical potential in the plane of the disk in such a way as to counteract the halo ellipticity. We develop a technique to calculate the equilibrium configuration of such a disk in the

The Music of Spheres [ God as A Geometer ] [PDF]
Anastasis: Research in Medieval Culture and Art, 2014 The rediscovery and enhancement of the standards, canons or constructive techniques of the pictorial space used by the masters of the traditional periods in art history, could be a viable alternative to the identity crisis that defines contemporary art ...

Halo Coupling and Cleaning by a Space Charge Resonance in High Intensity Beams
, 2013 We show that the difference resonance driven by the space charge pseudo-octupole of high-intensity beams not only couples the beam core emittances; it can also lead to emittance exchange in the beam halo, which is of relevance for beam loss in high ...

On the origin of cold dark matter halo density profiles [PDF]
, 2005 N-body simulations predict that CDM halo-assembly occurs in two phases: 1) a fast accretion phase with a rapidly deepening potential well; and 2) a slow accretion phase characterised by a gentle addition of mass to the outer halo with little change in ...

The Stellar Halo in the Large Magellanic Cloud: Mass, Luminosity, and Microlensing Predictions
, 2003 Recently obtained kinematic data has shown that the Large Magellanic Cloud (LMC) possesses an old stellar halo. In order to further characterize the properties of this halo, parametric King models are fit to the surface density of RR Lyrae stars.

Combining perturbation theories with halo models
, 2011 We investigate the building of unified models that can predict the matter-density power spectrum and the two-point correlation function from very large to small scales, being consistent with perturbation theory at low $k$ and with halo models at high $k$.
