Caption: Probing (slow) warm absorbers and (fast) massive outflows in AGN. Simulated 100 ks X-IFU spectrum of PDS456 (z=0.184) above 4 keV obtained assuming a source state as in the XMM+NuSTAR observations of PDS456 as shown in Reeves et al. (2018). We assumed here a soft X-ray absorber with a turbulence velocity of 300 km/s and an ultra-fast wind component with a turbulence velocity of 3000 km/s. The soft wind has a column density of ~2x1022 cm-2 and ionization of log ξ=3.1 and is outflowing with v~0.2 c. The ultra-fast wind has a column density of ~1.5x1023 cm-2, log ξ=3.6 and vout~-0.24c.

Additional comments: The model consists of a FeXXV emission line at ~5.9 keV observed frame, i.e. 6.8 keV rest-frame, with sigma=0.3 keV, i.e. an ionized emission line produced by an accretion disk (thus broad) and/or by a fast outflowing wind producing a broad P-Cygni like profile.

The absorption lines are:

• at 6.6 keV (observed energy frame): FeXXIV/XXV (Li/He α) at v=0.2c and vturb=300 km/s from soft wind component with Nsw =2x1022 and log ξ=3.1.
• at 7.1 keV (observed energy frame): FeXXV Heα at v=0.24c and vturb=3000 km/s from “hard” wind component with Nhw=1.5x1023, and log ξ = 3.6
• at 7.5 keV (observed energy frame): FeXXVI Lyα at v=0.24c and vturb=3000 km/s from “hard” wind component with Nhw=1.5x1023, and log ξ= 3.6
• at 8.4 keV (observed energy frame): FeXXV Heβ at v=0.24c and vturb=3000 km/s from “hard” wind component with Nhw=1.5x1023, and log ξ = 3.6
• at 8.9 keV (observed energy frame): FeXXVI Lyβ at v=0.24c and vturb=3000 km/s from “hard” wind component with Nhw=1.5x1023, and log ξ = 3.6.
