Measuring strong gravity effects in AGN observed with LOFT

[presentation]

Thanks to its sensitivity and broad energy range (2-50 keV), LOFT will be able to determine with very high signal to noise and accurate continuum subtraction the profile of the Fe K-lines in AGN. In this talk we will present detailed simulations showing that LOFT-LAD observations will provide a high enough S/N to detect broad Fe lines in up to ~1 mCrab flux, measuring the inner radius of the disc down to the marginally stable orbit and, from this, derive the spin of the BH with high accuracy (10% for the fast spin). Moreover the very high throughput of LOFT will permit to investigate the Fe line response to flares, and reveal the orbital motion of the individual blobs providing BH mass and spin with 25% and 20% accuracy. We will also present a comparison of the LOFT performance with that available in the near future with XMM-Newton and NuStar combined observations.
