More than half of all nearby elliptical galaxies contain modest amounts (103 − 105 M⊙) of ionized gas. In bright elliptical galaxies this gas appears to lie in a rotating, kiloparsec-scale central disk, with a spectrum characteristic of non-thermal ionization. Low-luminosity ellipticals have a clumpy gas distribution and the gas in these galaxies is photoionized by young stars.
