[72.03] XMM-Newton Observations of NGC4151

R.E. Griffiths, A. Ptak (Carnegie Mellon University)

We present observations of NGC4151 using XMM-Newton, with results in the following areas:

(i) complex iron-line emission, interpreted in terms of the accretion disk and strong gravitational effects near the central black hole

(ii) a low-energy X-ray spectrum containing a strong oxygen line

(iii) the ultraviolet image obtained using the XMM Optical Monitor.

Variability of the X-ray spectrum and line emission has been studied during the 70Ks observation.
