    Enigma of ultraluminous X-ray sources may be resolved by 3D-spectroscopy (MPFS data)

    The ultraluminous X-ray sources (ULXs) were isolated in external galaxies for the last 5 years. Their X-ray luminosities exceed 100-10000 times those of brightest Milky Way black hole binaries and they are extremely variable. There are two models for the ULXs, the best black hole candidates. 1. They are supercritical accretion disks around a stellar mass black hole like that in SS433, observed close to the disk axes. 2. They are Intermediate Mass Black Holes (of 100-10000 solar masses). Critical observations which may throw light upon the ULXs nature come from observations of nebulae around the ULXs. We present results of 3D-spectroscopy of nebulae around several ULXs located in galaxies at 3-6 Mpc distances. We found that the nebulae to be powered by their central black holes. The nebulae are shocked and dynamically perturbed probably by jets. The nebulae are compared with SS433 nebula (W50).Comment: Proceedings of the ESO and Euro3D Workshop "Science Perspectives for 3D Spectroscopy", Garching (Germany), October 10-14, 2005. M.

    This article is a review of the book entitled Identity Formation in the New Testament (edited by Bengt Holmberg and Mikael Winninge, Mohr Siebeck, TĂĽbingen, 2008). It is a collection of various articles using intertextuality, literary theory (and social identity approaches), gender studies andpostcolonial theory when investigating identity formation in the New Testament

    Looking for Parametric Correlations within Faroese

    This paper first reviews some parameters that have been suggested to account for variation within Scandinavian, focussing for concreteness on the parameters proposed by Holmberg and Platzack (1995) and Bobaljik and Thráinsson (1998). As this review shows, Faroese is not as well behaved as the parametric approach to Scandinavian syntax would lead us to expect. In addition, the variation found within Faroese syntax is often gradient and not as categorical as the conventional parametric approach to variation would predict. Yet it can be shown that some of the correlations predicted by Holmberg and Platzack’s (1995) Agr Parameter and Bobaljik and Thráinsson’s (1998) Split IP Parameter are found in Faroese syntax and they are turn out to be statistically significant. In the final section it is argued that to account for facts of this sort we need to revise our ideas about parametric variation, language acquisition and the nature of internalized grammars — and that this will be necessary regardless of what we think of the particular formulation of parameters assumed by Holmberg and Platzack on the one hand and Bobaljik and Thráinsson on the other
