Quasi-periodic oscillations (QPOs) are often present in the X-ray flux from accreting stellarmass black holes (BHs). If they are due to relativistic (Lense-Thirring) precession of an inner accretion flow which is misaligned with the disc, the iron emission line caused by irradiation of the disc by the inner flow will rock systematically between red and blue shifted during each QPO cycle. Here we conduct phase-resolved spectroscopy of a ∼ 2.2 Hz type-C QPO from the BH X-ray binary GRS 1915+105… 

Spectral and Timing Properties of H 1743-322 in the “Faint” 2005 Normal Outburst

H 1743-322 is a well-known black hole X-ray binary (BH XRBs) that has been observed in several outbursts over the past. In this work, we have performed the spectral and timing analysis of H 1743-322

Probing black-hole accretion through time variability

Flux variability is a remarkable property of black hole (BH) accreting systems, and a powerful tool to investigate the multi-scale structure of the accretion flow. The X-ray band is where some of the
