The optical to soft X-ray spectrum of the ultrasoft broad-line AGN RE J2248-511
R. L. C. Starling, E. M. Puchnarewicz, E. Romero-Colmenero +1
We present a series of monitoring observations of the ultrasoft broad-line AGN RE J2248-511 with XMM-Newton. Previous X-ray observations showed a transition from a very soft state…

Do NLS1s and ultrasoft AGN have irradiated, warped accretion disks?
E. M. Puchnarewicz, R. Soria
When Beppo-SAX measured the 0.1--12 keV spectrum of RE J1034+396, observations in the optical, UV and EUV were also taken within a few weeks. This multiwavelength spectrum placed v…

BeppoSAX observations of Narrow-Line Seyfert 1 galaxies:I. Ton S 180
A. Comastri, F. Fiore, M. Guainazzi +10
We report on the first spectrum up to 10 keV of the bright narrow-line Seyfert 1 galaxy Ton S 180, obtained with the imaging instruments onboard BeppoSAX. This is the first observe…
