We present a spectral analysis of the NuSTAR and XMM-Newton observations of the Seyfert 1h galaxy/ULIRG IRAS 05189–2524 taken in 2013 .
We find evidence for relativistic disk reflection in the broadband X-ray spectrum : a highly asymmetric broad Fe K \alpha emission line extending down to 3 keV and a Compton scattering component above 10 keV .
Physical modeling with a self-consistent disk reflection model suggests the accretion disk is viewed at an intermediate angle with a super-solar iron abundance , and a mild constraint can be put on the high-energy cutoff of the power-law continuum .
We test the disk reflection modeling under different absorption scenarios .
A rapid black hole ( BH ) spin is favored , however we can not place a model-independent tight constraint on the value .
The high reflection fraction ( R _ { ref } \simeq 2.0–3.2 ) suggests the coronal illuminating source is compact and close to the BH ( lying within 8.7 R _ { g } above the central BH ) , where light-bending effects are important .
