Does Mrk 79 have an intermediate spin black hole

Robust measurements of black hole spin in supermassive black holes that are notrapidly rotating is difficult because of selection effects and technicalchallenges. We propose to observe the bright Seyfert 1 galaxy, Mrk 79, withNuSTAR and XMM, to confirm or correct the existing measured spin parameter ofa*virgul0.7, which is based on multiepoch XMM and Suzaku observations. Thoughmeasurements from the multiepoch analysis are precise, some parameters (e.g. photon index and reflection fraction) appear unusual when compared with typicalAGN values. The sensitivity above 10 keV provided with NuSTAR will let usdirectly constrain the primary continuum and Compton hump. This will result inmore accurate measurements of the model parameters and a tighter constraint of the black hole spin. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
