RE J2248-511: not all variable, ultrasoft, X-ray AGN have narrow Balmer lines.
BREEVELD A.A., PUCHNAREWICZ E.M. and OTANI C.
Abstract (from CDS):
The change in the soft X-ray spectrum as observed in the ROSAT and ASCA data is consistent with the behaviour of Galactic Black Hole Candidates (GBHCs) as they move from a high to a low state, i.e. a fall in the ultrasoft component and a hardening of the X-ray continuum. This GBHC analogy has also been proposed for NLS1s. Alternatively, the variability may be caused by opacity changes in a hot, optically thin corona which surrounds a cold, dense accretion disc; this was first suggested by Guainazzi et al. for 1H 0419-577, an object which shows remarkably similar properties to RE J2248-511.
