Abstract
We have observed the canonical gigahertz-peaked spectrum source 0108+388 with the Very Long Baseline Array at a range of frequencies above and below the spectral peak. The activity that dominates the radio emission from 0108+388, which is also classified as a compact symmetric object, is thought to be less than 1000 years old. We present strong evidence that the spectral turnover in 0108+388 results from free-free absorption by nonuniform gas, possibly in the form of a disk in the central tens of parsecs.
