Title Understanding the gamma-ray loud Narrow-Line Seyfert 1 Galaxies

Author Dr Luigi Foschini
Description We ask for 41 ks exposure to observe three Narrow-Line Seyfert 1 Galaxies (NLS1s) that have been detected at high-energy gamma rays (E>100 MeV) with Fermi-LAT. The selected targets have been poorly or never detected at X-rays and the requested observations, bringing also optical-to-UV data from the Optical Monitor, will allow us to build simultaneous optical-to-X-ray spectral energy distributions (SEDs), which will be complemented with Fermi data. We will calculate the jet and the accretion power from these data and compare with other active nuclei with or without jets, in order to better understand both how jets are generated and the nature of NLS1s.

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.
