|Title||TESTING THE MAGNETIC FLUX PARADIGM WITH RADIO INTERMEDIATE QUASARS|
|Author||Dr Karri Koljonen|
|Description||In this proposal, we seek to test the new magnetic flux paradigm for AGN jet production, which claims that the magnetic flux threading the black hole is the dominant factor determining the wide distribution of observed jet powers. We propose to constrain the black hole spin values of two radio intermediate quasars by using joint NuSTAR-XMM observations, and compare them to the jet magnetic flux measurements obtained via radio observations with the Very Long Baseline Array. The jet production efficiency in these sources is lower compared to powerful radio-loud quasars and we aim to find out, if this is due to their low black hole spin value, or them having failed to accumulate enough magnetic flux.|

|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.
