Iron K features in the hard X-ray XMM-Newton spectrum of NGC 4151
N. J. Schurch, R. S. Warwick, R. E. Griffiths +1
Recent XMM-Newton observations have measured the hard (2.5-12 keV) X-ray spectrum of the well-known Seyfert galaxy NGC 4151 with a signal-to-noise unprecedented for this source. We…
XMM-Newton observations of Broad FeKalpha emission from a Seyfert 1.9 galaxy MCG-5-23-16
G. C. Dewangan, R. E. Griffiths, N. J. Schurch
XMM-Newton observations of the bright Seyfert 1.9 galaxy MCG-5-23-16 have revealed a broad FeKalpha emission line which is nearly symmetric in contrast to the broad and red-shifted…
X-ray Fluctuation Power Spectral Densities of Seyfert 1 Galaxies
A. Markowitz, R. Edelson, S. Vaughan +11
By combining complementary monitoring observations spanning long, medium and short time scales, we have constructed power spectral densities (PSDs) of six Seyfert~1 galaxies. These…
