Spectroscopy of GRS 1915 + 105
We analyzed RXTE data of GRS 1915+105 of X-ray low states between 1996 and 1998. The X-ray spectrum is dominated by the power law component. We found (i) that the power law is pivoting at 10-30 keV, (ii) that the power law slope correlates with radio flux, (iii) three different groups of 3-10 keV residuals, (iv) that one of these residual groups correlates with the power law slope. The prototyp...
متن کاملBlack hole spin in GRS 1915 + 105
Microquasars are galactic black hole binary systems with radio jets which can sometimes be spatially resolved to show superluminal motion. The first and best known of this class of objects is GRS 1915+105, the brightest accreting source in our Galaxy. There is persistent speculation that strong jet emission could be linked to black hole spin. If so, the high spin should also be evident in accre...
متن کاملInfrared synchrotron oscillations in GRS 1915 + 105
We report simultaneous observations of the black hole candidate X-ray transient GRS 1915+105 in the infrared at K and in the radio at 2 cm. Oscillations of period 26 min were observed in both wavebands, having (dereddened) peak–peak amplitudes of about 40 mJy and with the IR leading the radio by 7 min, or perhaps by 33 or 59 min. A synchrotron origin for the oscillations continues to seem very ...
متن کاملSuper-eddington Accretion in Grs 1915+105
Classical modelling suggests that, during the RXTE observations studied, GRS 1915+105 was near or above the critical accretion rate and the optically thick inner disk penetrated inside the advection-dominated flow. The system was very unstable leading to a rich pattern of variability , e.g. the rings which might be characteristic to disk instabilities very close to the innermost stable orbit. S...
متن کاملGrs 1915+105: Ten Years After
It is now ten years since the first microquasar GRS 1915+105 was discovered. More than six years of observations with RossiXTE have shown a level of variability never observed in any other X-ray source. Here I try to address some issues, based on X-ray observations only, that have relevance for theoretical modeling. First, I ignore these peculiarities and concentrate on the similarities with ot...
