NGC3894 is one of the only three gamma-ray loud young radio sources and aCompton-thick AGN candidate. This combination makes it uniquely suitable toinvestigate the origin of the X-ray and high-energy emission in young radiosources and the feedback of the expanding source in a dense medium. We request70 ksec XMM observation to confirm the tentative detection of Fe Kalpha emissionline reported with Chandra. The X-ray continuum will be jointly modeled the XMMdata with our existing NuSTAR data, allowing us to differentiate betweenreflection vs direct emission as the dominant X-ray spectral component. TheX-ray spectrum and radio-to-gamma-ray data will enable tests of radiative anddynamical models for young radio sources with implications for an early feedback process with host galaxy.

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.
