The Suzaku view of Cyg X-1 over the two spectral states
Abstract
We conducted 25 Suzaku observations of Cyg X-1 in the Low/Hard State, with a total exposure of about 450 ks, Here, we analyzed the data from the Hard X-ray Detector (HXD). From results obtained from spectral and timing analysis, we derived some picture of evolution of the accretion flow in the Low/Hard State, and the cool disk to intrude more deeply therein (Torii et al. 2011). On 2010 December 16, a Suzaku ToO observation of Cyg X-1 was performed to benefit from the most recent High/Soft State found with MAXI. A brief analysis of the data is presented in this paper.
