Mrk 876 and the spin of its Supermassive Black Hole

Mrk 876, also known as PG 1613+658, is a Sy1 AGN. We present the results of the observations with XMM-Newton, Chandra, Swift/XRT, and NuSTAR, which is the most recent observation. We will focus on the timing and spectral analyses, which bring to light reflection features off the accretion disk that display the effects of General Relativity due to gravitational potential. Monte Carlo simulations establish the significance of the features. The inferred parameters are compared to other independent measurements. Due to the rather low NuSTAR exposure the derived spin is an upper limit. We will show simulations for possible longer observations.
