SUMMARY:Cosmology on a Moving Mesh\, Distinguished Lecture Series\, La
rs Hernquist\, Harvard University
DESCRIPTION:
\nUnderstanding the formation and evolution of galaxi
es in a cosmological context using numerical simulations remains an el
usive goal. In this talk\, I describe a new approach to modeling the
hydrodynamics of galaxy formation in which the equations of motion are
solved on a moving mesh. The use of a moving mesh makes the scheme f
ully Lagrangian\, unlike popular particle-based codes which are quasi-
Lagrangian in nature\, and mitigates against advection errors when a s
patially fixed grid is used. I present results from an initial study
comparing results for a moving mesh with those obtained using a smooth
ed particle hydrodynamics solver. This preliminary work suggests that
the new approach offers promise for resolving the long-standing probl
ems which have plagued this field for nearly two decades.
