Query: Comptonization and reflection of X-ray radiation and the X-ray-radio
  correlation in the chi-states of GRS 1915+105   We present a comprehensive X-ray study of four years of pointed RXTE
observations of GRS 1915+105 in the chi-state. We interpret the behavior of the
hard power law tail spectrum as coming from inverse Compton scattering of soft
disk photons on a thermally dominated hybrid corona above the accretion disk.
GRS 1915+105 shows a strong, variable reflection amplitude. As in other BHC and
in Seyfert galaxies, a correlation between the power law slope and the
reflection was found. Also, the radio fluxes at 2.25 GHz and 15 GHz correlate
with the power law slope, thus revealing a connection between the outflowing
matter and the comptonizing region in the chi-states.
