On the behaviour of streams in angle and frequency spaces in different potentials
Hans J. T. Buist, Amina Helmi
We have studied the behaviour of stellar streams in the Aquarius fully cosmological N-body simulations of the formation of Milky Way halos. In particular, we have characterised the…

The evolution of streams in a time-dependent potential
Hans J. T. Buist, Amina Helmi
We study the evolution of streams in a time-dependent spherical gravitational potential. Our goal is to establish what are the imprints of this time evolution on the properties of…

A new fitting-function to describe the time evolution of a galaxy's gravitational potential
Hans J. T. Buist, Amina Helmi
We present a new simple functional form to model the evolution of a spherical mass distribution in a cosmological context. Two parameters control the growth of the system and this…
