A detailed study of two NLS1

Narrow Line Seyfert 1 galaxies have strong spectral features in the 0.110keVband and strong variability, making them very interesting XMM targets. These properties are probably due to the emission orginating in the inner regions ofionized disks around massive black holes. We propose to observe two typicalNLS1, PG 1244 and PG 1404, in order to test this hypothesis using spectral models of ionized disks developed by us. If correct, the oxygen features offera further means to determine the relativistic Xray line broadening. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
