Thermal/Non-thermal Comptonization Spectral Fits to GRS 1915+105
Abstract
We present the results from thermal/non-thermal Comptonization model fits for a variety of hard state observations of GRS 1915+105 taken with RXTE. The model fits all observations reasonable well, regardless of whether the source was in the hard or soft state and regardless of the radio loudness of the observation. We demonstrate that this model predicts larger blackbody components and hence more physically reasonable inner radii than the standard disk blackbody plus power law. We also discuss the correlation between the strength of the non-thermal component and the radio intensity of the source.
