AbstractA fair fraction of Galactic stellar-mass black holes are reported to be rapidly spinning, based on their broad Fe-K lines. However, such broad features couple strongly with the spectral continuum, and cause the modeling to degenerate. By carefully analyzing broad-band Suzaku data, and also employing the information on optically-thick disk emission, GX 339-4 is inferred to harbor a low-spin black hole. In addition, the Suzaku spectra of the Seyfert galaxy MCG-6-30-15 are interpreted in an alternative way, without invoking the rapid black-hole spin.
