Abstract | The discovery by Fermi-LAT of variable gamma-ray emission from 4 radio-loudNarrow Line Seyfert 1 revealed the presence of an emerging third class ofgamma-ray emitting AGNs. This poses intriguing questions on the knowledge of theUnified model of AGNs, the development of relativistic jets, the disc/jetconnection, and the evolution of radio-loud AGNs. We propose a 90 ksecXMM-Newton observation of the first RL-NLS1 detected in gamma-rays by Fermi-LAT:PMN J0948+0022. The XMM-Newton satellite, thanks to the high sensitivity of theEPIC cameras and the broad band coverage from optical to X-rays, creates aperfect synergy with Fermi for a complete understanding of properties of thisprototypical gamma-ray radio-loud Narrow Line Seyfert 1. |

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. |
