|Title||ILLUMINATING THE DISK-CORONA-JET CONNECTION IN NLS1 GALAXIES|
|Author||Dr LAURA BRENNEMAN|
|Description||We propose a 200-ks NuSTAR observation of the radio-loud narrow line Seyfert 1 galaxy PMN J0948+0022, to be executed contemporaneously with an 80-ks XMM-Newton observation. The high accretion rate and rapid variability of NLS1s make them ideal candidates in which to observe the disk-corona system, but there are only a small handful of radio-loud members of this population. The broadband X-ray and optical-UV spectra we obtain, along with information from existing Fermi and radio campaigns, will allow us to address some of the key questions regarding the physics of jet formation in this critical sample, such as the physical conditions under which a jet can be launched, the relation of the jet to the putative corona in AGN, and correlations with the inner 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.
