Description | We propose to perform (as a ToO) a series of 4x10ks+2x40 ks joint XMM-Newton/NuSTAR observations (spaced by a few days) of a microquasar during its outburst decline phase to follow its broadband X-ray spectral evolution with an unprecedented precision. We will perform simultaneous radio, optical and IR observations to observe the reactivation of the jet. This will allow us i) to carefully investigate the physical/geometrical changes of the disc/corona system through the transition and ii) to reveal the drivers of the quenching/reappearance of the jets during the state transitions and how they connect to the properties of the accretion flow. |

Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
