Abstract	PG1448+273 is a luminous Narrow Line Seyfert 1 galaxy, thought to be accretingat the Eddington limit. An XMM-Newton observation in 2017 captured an ultra fastoutflow in PG1448+273, via a deep Fe absorption trough between 7-8 keV, with anoutflow velocity of 0.1c. The AGN has never been observed at hard X-rays. Wepropose a simultaneous NuSTAR (120 ks) and XMM-Newton (75 ks) observation toquantify the physical properties of the fast wind. The observations will; (i)provide a realistic estimate of the mass outflow rate and wind energetics, (ii)probe variations in the wind in response to the continuum and (iii) measure thebroadband SED and quantify the mass accretion rate and Eddington ratio. Theobservations will test the plausibility of radiation driven winds near the Eddington limit.

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.
