Abstract We propose a 40ksec joint XMM-Newton/NuSTAR observation of the black hole binarySwift J1753.5-0127 in its persistent faint low/hard state. This will constrainthe radial stratification of the corona and the spectral curvature of thelow/hard state continuum in the unprecedented 0.7-70keV band. This will thengive the most unambigious measure of the strength of the soft X-ray componentand resolve some of the controversies over the accretion geometry. Theobservation will also help with ongoing calibration/cross- calibration effortsfor both satellites. This observation is not time critical, and will be feasiblewhen it best suits the satellites schedules. An ongoing AMI LA radio monitoringprogramme of Swift J1753.5-0127 will be adapted to coincide with this XMM-Newton/NuSTAR observation.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
