Title: 
The effects of a smoothly growing galaxy on the evolution and properties streams
Abstract: 

We investigate the effect on streams of a smoothly growing galaxy using test-particle simulations, using a cosmologically motivated time-dependent potential. Streams consist of stars that orbit the galaxy on similar trajectories, therefore responding mostly to the galactic potential. As the galaxy grows in mass, the enclosed mass within the orbit of the stream changes. We find this to have an effect on the evolution and properties of the stream.
