摘要：

The extended emission-line nebulae surrounding the central galaxies of the Perseus and Centaurus clusters show a direct association with soft X-ray filaments indicating an energy exchange between the hot intracluster medium and the warm ionized gas. Radial gradients in the [NII]/H alpha ratio imply the ionization state of the line-emitting gas is coupled to the global properties of the intracluster medium or the gas contains significant metallicity variations. The velocity field of filaments within the Perseus cluster core indicate that the filaments are most likely to be galactic gas drawn out of the central galaxy by the buoyant rise of under-dense bubbles.
