As hybrids of NLS1s and blazars, the gamma-ray-emitting NLS1s provide a newperspective to investigate the properties and formation of jets and theircoupling with accretion. However, such objects are very rare. Only few NLS1shave been significantly detected in the gamma-ray band and studied so far. Wepropose a XMM observation on a new gamma-ray NLS1 which we have discovered usingBOSS and TripleSpec spectra. With a redshift of z=1, this object is the mostdistant among its kind. The observation will enable us to complete its missingX-ray information for the first time and provide key data for constructing itsbroad band SED. Its high-z may allow us to address black hole growth in suchrare kind of objects.

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.
