| Abstract | PG1448+273 is a luminous NLS1, thought to be accreting at the Eddington limit.An XMM observation in 2017 discovered an ultra fast outflow (v=0.1c) in PG1448,via a deep Fe absorption trough at 7.5 keV. A 2022 NuSTAR observation thenrevealed a drastic increase in wind velocity, to 0.3c, coincident with apronounced drop in flux. Here we wish to further understand the extremevariability of the disk wind, through 3x80ks and 3x50ks simultaneous XMM andNuSTAR observations, to determine the wind changes in velocity and outflow ratevs flux. A 40x1ks Swift daily monitoring campaign is proposed to monitor the UVto X-ray SED over the XMM window, to help determine how the wind reacts to thecontinuum. The observations will test the physics of accretion disk 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. |
