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

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.
