| Description | The discovery of gamma-ray emission from radio-loud narrow line Seyfert 1s (RL-NLSy1) by Fermi LAT confirmed that relatively small black holes with high accretion rates and late-type host galaxies can produce relativistic jets as powerful as those in bright blazars. This raises intriguing questions about the conditions required for jet formation. To study these conditions we propose an 80 ks XMM-Newton observation of the RL-NLSy1 FBQS J1644+2619, a new member of the small class of gamma-ray emitting RL-NLSy1s. With the proposed observation we will be able to determine the relative contribution of the jet and corona/accretion disc to the spectrum and, if the latter component is sufficiently strong, place constraints on the properties of the accretion flow. |

| 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. |
