Description We propose simultaneous (NuSTAR+XMM) ToO observations of a newly discovered
tidal disruption flare (TDF) to constrain its supermassive black holea??s (SMBH)
mass and spin. Our primary goals are to (1) detect X-ray quasi-periodic
oscillations (QPOs), and (2) study the role of the disk (using XMM) and the
corona (with NuSTAR) in exciting TDF QPOs. In the presence of an independent
SMBH mass estimate, the QPO frequency will provide a strict lower limit to the
spin, while in the absence of a mass constraint the QPO timescale will set a
tight upper limit on the SMBH mass. With excellent timing capabili-ties and the
ability to carry out continuous observations, NuSTAR and XMM are ideally suited
for this study whose ultimate goal is to use TDF QPOs to measure several SMBH spins.

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.
