| Abstract | We request 80 ks of XMM-Newton and 40 ks of NuSTAR time to trigger Target ofOpportunity (ToO) observations of a new or known black hole transient during theend of its outburst, after the source has entered the low-hard state. We aim toobtain high signal-to-noise data during this fainter phase in order to measurethe level of disk truncation using X-ray reflection spectroscopy. We will alsoprovide measurements for the disk inclination, ionization and iron abundance.These observations will provide crucial constraints to support a large-scaledata analysis program for these sources. |

| 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. |
