We propose two 30ks XMM-Newton observations of the luminous (L_0.1-2 keV=4x10^44erg/s) NLS1 RX J0134.2-4528. This object has unusual optical and UVemission-line properties that are consistent with an X-ray weak spectral energydistribution illuminating the broad-line region. The proposed observations willprovide the first reliable measurement of alpha_ox. The EPIC observations willreveal X-ray spectral complexity that is common in XMM-Newton observations ofNLS1s. These observations will be used to determine the intrinsic X-ray emissionthrough spectral variability analysis, and through comparison with both theX-ray and UV emission-line properties of a sample of NLS1s.

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.
