|Title||Tracing the evolution of BH winds through the intermediate states|
|Author||Dr Gabriele Ponti|
|Description||Black hole transients (BHT) are the only class of black holes (BH) which samples a wide range of accretion rates and accretion states during their month to year long outbursts. BHT classically show two types of outflows: collimated radio-jets ubiquitous during the canonical hard state and highly ionised X-ray winds during the soft state. We propose a combined XMM+NuSTAR monitoring campaign of an high inclination BHT, to shed light on the evolution of the wind while the source transits through the intermediate states.|

|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.
