VLBI observations of scintillation arcs

August 29

12:10PM, Room 230, NRAO, Edgemont Road


The discovery of scintillation arcs has led to an improved understanding of pulsar scattering. Here we attempt to go one step further and use VLBI to "image" the scattering surface. The anisotropy and power spectrum of turbulence on AU and smaller scales can perhaps be probed.
