Imaging the event horizon of Sgr A*?

Figure 1: The black hole in the Galactic Center - if it is one - is big and close enough to image its event horizon, or `shadow', with existing technology. This is argued in a paper by Falcke, Melia, & Agol (2000). The figure shows the appearance of the shadow of the black hole for Sagittarius A* against the compact radio emission. The images were calculated for the interstellar scattering and the instrumental resolution expected for upcoming sub-mm VLBI experiments (right: lambda=1.3mm, middle: lambda=0.6mm). In a second paper Agol argues that the polarization properties of Sgr A* (see article) strengthen that claim.
