This STIS spectral image shows the velocity
distribution of the carbon emission from the gas in the core of NGC 4151. Itrequires more energy to make the carbon gas glow (CIV at 1549 Angstroms)
than it does to ionize the oxygen gas seen in the other images. This means we expect that the carbon emitting gas is closer to the heart of the energy source.
