Evidence for a high accretion rate as the defining parameter of Narrow-Line Seyfert 1 galaxies

Abstract

X-ray spectral features which are unusually strong in many Narrow-Line Seyfert galaxies are found to be consistent with reflection from strongly ionized matter, providing further evidence of a high accretion rate in these objects and offering a unique signature of that key parameter in future observations.
