X-ray spectral components in the hard state of GRS 1915+105: origin of the 0.5 - 10 Hz QPO

A. R. Rao, S. Naik, S. V. Vadawale +1

We investigate the origin of the ubiquitous 0.5 - 10 Hz QPO in the Galactic microquasar GRS 1915+105. Using the archival X-ray data from RXTE, we make a wide band X-ray spectral fi…
