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 blackhole mass and high accretion objects are desirable. We therefore propose a 20 ksec XMMNewton observation of a NarrowLine 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.
