Title A Detailed Study of One Extreme NLS1: PG 1244+026


DOI 10.5270/esa-y2i21uh
Author Mr Chichuan Jin
Description PG 1244+026 is a an extremely bright active galaxy (AGN) with the narrowest H-beta line among all PG quasars. Its broadband spectral energy distribution (SED) shows a huge soft X-ray excess making this object a perfect test for our models of NLS1 which are dominated by large hot discs. Here we propose to observe this object in order to study its X-ray spectrum and spectral variability. A long exposure time XMM-Newton observation will resolve detailed features in its X-ray spectrum and RMS spectrum, especially in the soft-excess region. This study will help us to understand the nature of the most extreme NLS1s, and provide essential evidence towards the unification of the accretion processes between AGN and black hole binaries (BHBs).

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.
