Misalignment of the microquasar V4641 Sgr (SAX J1819.3--2525)
Rebecca G. Martin, Rubens C. Reis, J. E. Pringle
In the microquasar V4641 Sgr the spin of the black hole is thought to be misaligned with the binary orbital axis. The accretion disc aligns with the black hole spin by the Lense-Th…
A systematic look at the Very High and Low/Hard state of GX 339-4: Constraining the black hole spin with a new reflection model
R. C. Reis, A. C. Fabian, R. Ross +3
We present a systematic study of GX 339-4 in both its very high and low hard states from simultaneous observations made with XMM-Newton and RXTE in 2002 and 2004. The X-ray spectra…
Initial Measurements of Black Hole Spin in GX 339-4 from Suzaku Spectroscopy
J. M. Miller, C. S. Reynolds, A. C. Fabian +6
We report on a deep Suzaku observation of the stellar-mass black hole GX 339-4 in outburst. A clear, strong, relativistically-shaped iron emission line from the inner accretion dis…
