GRS 1915+105: The brightest Galactic black hole

We compare the evolution of spectral shape with luminosity in GRS 1915+105 with that of 'normal' black holes. The pathological time variability of GRS 1915+105 does not indicate that it belongs in a different class to all the other objects. At comparable fraction of Eddington luminosity it...

Description
Summary:We compare the evolution of spectral shape with luminosity in GRS 1915+105 with that of 'normal' black holes. The pathological time variability of GRS 1915+105 does not indicate that it belongs in a different class to all the other objects. At comparable fraction of Eddington luminosity its spectra and (more importantly) time variability behaviour are similar to that seen in the 'normal' black holes. Its unique limit-cycle variability only appears when it radiates at uniquely high (super-Eddington) luminosities.
