Abstract	As hybrids of NLS1s and blazars, the recently discovered gamma-ray emittingNLS1s excited a great interests to the AGN community. With relatively smallblack hole (BH) mass and accreting close to Eddington, these NLS1s provides anew perspective to investigate the properties and formation of jets and theircoupling with BH accretion. However, gamma-ray emitting NLS1s are rare and thereare only sevend significantly detected in the gamma-ray band and being studiedso far. We propose to observe a newly discovered gamma-ray NLS1 with XMM-Newtonin the X-ray, UV and optical bands. These observations will help to complete themissing X-ray spectral and temporal information and constructing its broad bandSED, which are crucial for modeling and constraining the jet parameters in this object.

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.
