    "abstract": "We extend an isothermal thermal model of ultracold neutral plasma expansion\nto systems without spherical symmetry, and use this model to interpret new\nfluorescence measurements on these plasmas. By assuming a self-similar\nexpansion, it is possible to solve the fluid equations analytically and to\ninclude velocity effects to predict the fluorescence signals. In spite of the\nsimplicity of this approach, the model reproduces the major features of the\nexperimental data.",
