Title PG 1448+273: The hottest accretion disk among Active Galactic Nuclei

Author European Space Agency
Description The switch from the standard accretion disk to the slim accretion disk
has 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 this
purpose, 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 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.
