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 asymmetric FeKalpha line sometimes observed from Seyfert 1 galaxies. The FeKalpha line has two distinct components - a narrow unresolved component with equivalent width of 40 eV and a broad component with full width at half maximum of 40000 km/s and equivalent width of 120 eV. An absorption feature at 7.1 keV has…

Relativistic Iron K Emission and Absorption in the Seyfert 1.9 Galaxy MCG –5-23-16
We present the results of the simultaneous deep XMM-Newton and Chandra observations of the bright Seyfert 1.9 galaxy MCG -5-23-16, which is thought to have one of the best known examples of a
The iron emission line complex of MCG-5-23-16: the long XMM-Newton look
We present the results of the simultaneous XMM-Newton and Chandra observations of the bright Seyfert 1.9 galaxy MCG–5-23-16, which is one of the best known examples of a relativistically broadened
An XMM–Newton survey of broad iron lines in Seyfert galaxies
We present an analysis of the X-ray spectra of a sample of 37 observations of 26 Seyfert galaxies observed by XMM–Newton in order to characterize their iron Kα emission. All objects show evidence for
A Simultaneous RXTE and XMM-Newton Observation of the Broad-Line Radio Galaxy 3C 111
We present the results of simultaneous XMM-Newton and RXTE observations of the broad-line radio galaxy 3C 111. We find that the Compton reflection bump is extremely weak; however, broad residuals are
Iron line spectroscopy of NGC 4593 with XMM–Newton: where is the black hole accretion disc?
We present an analysis of the 2-10 keV XMM-Newton/EPIC-pn spectrum of the Seyfert-1 galaxy NGC 4593. Apart from the presence of two narrow emission lines corresponding to the Ka lines of cold and
A possible ultra strong and broad Fe Ka emission line in Seyfert 2 galaxy IRAS 00521-7054
We present XMM-Newton spectra of the Seyfert 2 Galaxy IRAS 00521-7054. A strong feature at ~6 keV (observer's frame) can be formally fitted with a strong (EW=1.3+-0.3 keV in the rest frame) and broad
The reprocessing features in the X–ray spectrum of the NELG MCG –5-23-16
We present results from the spectral analysis of the Seyfert 1.9 galaxy MCG -5-23-16, based on ASCA, BeppoSAX, Chandra and XMM-Newton observations. The spectrum of this object shows a complex iron Kα
A prominent relativistic iron line in the seyfert 1 MCG-02-14-009
I report the discovery of a prominent broad and asymmetrical feature near 6.4keV in the Seyfert 1 MCG-02-14-009 (z = 0.028) with XMM-Newton/EPIC. The present short X-ray observation (PN net exposure
Revealing the High Energy Emission from the Obscured Seyfert Galaxy MCG−5–23–16 with Suzaku
We report on a 100 ks Suzaku observation of the bright, nearby (z=0.008486) Seyfert 1.9 galaxy MCG -5-23-16. The broad-band (0.4-100 keV) X-ray spectrum allows us to determine the nature of the high
The iron K line profile of IRAS 18325–5926
IRAS 18325−5926 is an X-ray bright, Compton-thin, type 2 Seyfert galaxy and it was the first Seyfert 2 in which the presence of a broad Fe Kα emission line was claimed. However, although the


Detecting Compton Reflection and a Broad Iron Line in MCG-5-23-16 with the Rossi X-ray Timing Explorer
We report the detection with the Rossi X-ray Timing Explorer of a Compton reflection signature in the Seyfert galaxy MCG-5-23-16. RXTE also resolves the Fe K-alpha fluorescence line with FWHM ~48,000
