We present the first radial velocity curve of the companion star to BW Cir which demonstrates the presence of a black hole in this X-ray transient which recorded outbursts in 1987 and 1997 (and possibly 1971-2). We identify weak absorption features corresponding to a G0-5III donor star, strongly veiled by a residual accretion disc which contributes 61-65 % of the total light at λ6300. The Doppl...

We present the results of a NuSTAR study of the dynamically confirmed stellar-mass black hole GS 1354−645. The source was observed during its 2015 “hard” state outburst; we concentrate on spectra from two relatively bright phases. In the higher-flux observation, the broadband NuSTAR spectra reveal a clear, strong disk reflection spectrum, blurred by a degree that requires a black hole spin of a...

Norway is an example of the Nordic model in which local level fundamental importance. However, municipalities are relatively small and increasingly subject to decentralisation their activities.
