Approaching the Event Horizon through VLBI Imaging of Sagittarius A*

Figure 1: From Doeleman & Bower's article. Major axis size, minor axis size, and position angle of elliptical Gaussian models for Sgr A* as a function of wavelength normalized by a lambda2 scattering law (solid line, Bower et al. 2004). The deviation in the short wavelength sizes from the scattering law indicates the detection of an intrinsic source size. Included is the 3.5 mm measurement in the major axis, also made with closure amplitude techniques. (See Article by Shep Doeleman & Geoff Bower).
