The soft X-ray component and the hard continuum curvature in black hole binaries
Abstract
We propose a 40ksec joint XMM-Newton/NuSTAR observation of the black hole binary Swift J1753.5-0127 in its persistent faint low/hard state. This will constrain the radial stratification of the corona and the spectral curvature of the low/hard state continuum in the unprecedented 0.7-70keV band. This will then give the most unambigious measure of the strength of the soft X-ray component and resolve some of the controversies over the accretion geometry. The observation will also help with ongoing calibration/cross- calibration efforts for both satellites. This observation is not time critical, and will be feasible when it best suits the satellites' schedules. An ongoing AMI LA radio monitoring programme of Swift J1753.5-0127 will be adapted to coincide with this XMM-Newton/NuSTAR observation.
