In this proposal, we seek to test the new magnetic flux paradigm for AGN jetproduction, which claims that the magnetic flux threading the black hole is thedominant factor determining the wide distribution of observed jet powers. Wepropose to constrain the black hole spin values of two radio intermediatequasars by using joint NuSTAR-XMM observations, and compare them to the jetmagnetic flux measurements obtained via radio observations with the Very LongBaseline Array. The jet production efficiency in these sources is lower comparedto powerful radio-loud quasars and we aim to find out, if this is due to theirlow black hole spin value, or them having failed to accumulate enough magneticflux.

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.
