Abstract	The switch from the standard accretion disk to the slim accretion diskhas long been a natural, theoretical consequence of high accretion rate.To test this paradigm, small black-hole mass and high accretion objects are desirable. We therefore propose a 20 ksec XMM-Newton observation of a Narrow-Line Seyfert 1 galaxy extremely suitable to thispurpose, PG 1448+273, to examine and derive constraints on the slim disk model, through detailed modeling of both spectral and temporal behaviors.

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.
