A high level of complex structure, or "granularity," has been observed in the distribution of infrared-obscuring material toward the Galactic center (GC), with a characteristic scale of 5''-15'', corresponding to 0.2-0.6 pc at a GC distance of 8.5 kpc. This structure has been observed in ISAAC images, which have a resolution of ~06, significantly higher than that of previous studies of the GC. We have discovered granularity throughout the GC survey region, which covers an area of 16 × 08 in…
