Colloquium: Noam Libeskind (AIP)

There’s no place like home: simulating the Local Group and understanding the structure of the cosmic near field

The local environment is a unique place - not in the copernican sense, but in the sense that it has a unique cosmography. The structure of the cosmic near field can be probed via the peculiar velocities of the objects that inhabit it. These observed peculiar velocities can be used to constrain initial conditions, within the LCDM paradigm, and then used to simulate Local Groups that are embedded in cosmic structures that bare a strong resemblance to reality. In this talk, I'll explain how one makes cosmographic maps, what the local cosmography looks like and why such a notion goes beyond map making and into the predictive field of numerical simulation, galaxy formation and the history of the Milky Way.
