## Abstract We explore the nature of ultraluminous Xβray sources through detailed investigations of their spectral shape using some of the highest quality data available in the XMMβNewton public archives. Phenomenological models allow us to characterise their spectra, while more βphysicallyβmotivat

The BeppoSAX High Energy Large Area Survey (HELLAS) has found so far 200 sources with a 5-10 flux higher than 5 Γ 10 -14 erg cm -2 s -1 in βΌ 80 deg 2 of sky. A summary on the optical identifications of a subsample of these sources is presented here. Most of the identified sources are AGN at 0.04<z<3
## Abstract The transient system SAX J1711.6β3808 was observed by XMMβNewton during its 2001 outburst, when the source was close to its maximum outburst luminosity. Our observations show that the broad Fe emission line detected in this outburst by In' t Zand et al. (2002) has indeed a relativistic
We present results of optical identifications of the X-ray sources detected in the ASCA Large Sky Survey.
