摘要: We present a spectral analysis of the narrow-line Seyfert 1 galaxy I Zwicky 1, focusing on characteristics ionised absorbers as observed with XMM-Newton in 2005. The outflow velocity X-ray low-ionisation absorber is consistent UV detected past Hubble Space Telescope observation. In addition, ionic column densities Civ and Nv derived from model are values. This suggests that outflowing gas may survive for many years, despite large changes flux, there tight connection between can only be confirmed simultaneous
