Galactic Halo Cusp versus Core: Tidal Effects in Mergers
Avishai Dekel, Jonathan Devor, Itai Arad
We show how the buildup of halos by merging satellites forces an inner cusp, with a density profile ρ\propto r^{-α} where α\to α_a \gsim 1$. Our analysis is based on a new prescrip…

Anomalous Scaling in Passive Scalar Advection and Lagrangian Shape Dynamics
I. Arad, I. Procaccia
The problem of anomalous scaling in passive scalar advection, especially with -correlated velocity field (the Kraichnan model) has attracted a lot of interest since the exponent…
