We propose a simultaneous observation with NuSTAR (150 ks) and XMM (75 ks) ofthe radio-quiet Narrow-Line Seyfert 1 galaxy PG 1402+261 (z=0.164), which showedsignificant spectral complexity at 6-9 keV in a previous XMM snapshot. This canbe interpreted as either a very strong, extremely broadened FeK emission linefrom the accretion disk, or the signature of a high-column, high-ionization diskwind. By pinpointing the intensity and shape of the continuum beyond thispuzzling feature, NuSTAR will allow us to distinguish between the two scenariosor disentangle their relative contribution. Indeed, PG 1402+261 is ahigh-luminosity (and possibly more extreme) equivalent of other NLS1s where bothstrong reflection and ultra-fast outflows have been recently revealed.

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.
