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

PG 1244+026 is a an extremely bright active galaxy (AGN) with the narrowestHbeta line among all PG quasars. Its broadband spectral energy distribution(SED) shows a huge soft Xray excess making this object a perfect test for ourmodels of NLS1 which are dominated by large hot discs. Here we propose toobserve this object in order to study its Xray spectrum and spectralvariability. A long exposure time XMMNewton observation will resolve detailedfeatures in its Xray spectrum and RMS spectrum, especially in the softexcessregion. This study will help us to understand the nature of the most extremeNLS1s, and provide essential evidence towards the unification of the accretionprocesses between AGN and black hole binaries (BHBs). truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
