Abstract
We present an analysis of XMM-Newton spectra of the low-redshift quasar IRAS 13349+2438. The Reflection Grating Spectrometer spectrum shows a large number of absorption lines from two zones of warm absorption, with velocities of ∼-600 km s-1, as noted by previous authors. Additionally, we find robust evidence from multiple Lyα absorption lines for a previously undiscovered ultrafast zone of absorption, with an outflow velocity of -0.13 ± 0.01c. The warm absorbers and ultrafast outflow have similar mass outflow rates, around 40{{ per cent}} of the Eddington accretion rate, but the kinetic power is dominated by the high-velocity gas that has a power of {∼ }4{{ per cent}} of the Eddington luminosity.d
