| Abstract | The detection of gamma-ray emission from narrow-line Seyfert 1 (NLS1) AGNconfirms the presence of powerful relativistic jets in these sources. NLS1s havemuch lower black hole (BH) masses and higher accretion rates than the majorityof blazars, therefore allowing investigations into how jets scale with the massand accretion rate of the BH. Studies in the XMM band have shown that the tailof the accretion flow emission is present in the soft X-rays, whilst the jetdominates at higher energies. Thus, with X-ray and UV observations we canparameterise the accretion flow and simultaneously probe the non-thermalemission from the jet. We propose the first XMM observations of sixnewly-discovered gamma-ray NLS1s to explore the disc-jet connection and address issues of jet scaling and power. |

| 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. |
