We examine the XMM X-ray spectrum of the low-ionisation nuclear emission-line region (LINER)-AGN NGC 7213, which is best fit with a power law, Kα emission lines from Fe i, Fe xxv and Fe xxvi and a soft X-ray collisionally ionised thermal plasma with kT = 0.18+0.03−0.01 keV. We find a luminosity of 7× 10−4 LEdd, and a lack of soft X-ray excess emission, suggesting a truncated accretion disc. NGC 7213 has intermediate X-ray spectral properties, between those of the weak AGN found in the LINER M… 

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 broad-line region origin for the iron Kα line in NGC 7213

The X-ray spectrum of NGC 7213 is known to present no evidence for Compton reflection, a unique result among bright Seyfert 1s. The observed neutral iron Kα line, therefore, cannot be associated with

X-RAY OUTFLOWS IN THE SWIFT BURST ALERT DETECTED SEYFERT 1s

Previous surveys of outflows in low-redshift active galactic nuclei (AGNs) have relied on the analysis of sources selected primarily for their optical/X-ray brightness and are therefore biased.

X-ray and radio variability in the low-luminosity active galactic nucleus NGC 7213

We present the results of a similar to 3 yr campaign to monitor the low-luminosity active galactic nucleus (LLAGN) NGC 7213 in the radio (4.8 and 8.4 GHz) and X-ray bands (2-10 keV). With a reported

X-ray emission line gas in the LINER galaxy M 81

We present the soft X-ray spectrum of the LINER galaxy M 81 derived from a long observation with the XMM- Newton RGS. The spectrum is dominated by continuum emission from the active nucleus, but also

We present an XMM-Newton observation of NGC 7469, including studies of the X-ray and UV variability, 0.2 10 keV spectral continuum, Fe K emission line and the first-ever high-resolution X-ray

A simultaneous XMM-Newton and BeppoSAX observation of the archetypal broad line Seyfert 1 galaxy NGC 5548

We report the spectral analysis of a long XMM‐Newton observation of the well-studied, moderate luminosity broad line Seyfert 1 galaxy NGC 5548. The source was at an historically average brightness

Highly ionized Fe Kα emission lines from the LINER galaxy M 81

We present spectral and timing results from a long (130 ks) XMM-Newton EPIC observation of the nucleus of the Seyfert/LINER galaxy M 81. During the observation the X-ray flux varied by 20%, but there

We present the first high-resolution, soft X-ray spectrum of the prototypical Seyfert 2 galaxy, NGC 1068. This spectrum was obtained with the XMM-Newton Reflection Grating Spectrometer (RGS).

Results are presented from Exosat observations of 48 hard X-ray selected Seyfert-type active galactic nuclei (AGN). These include all 30 of the emission line AGN in the Piccinotti (1981) sample.

We evaluate narrow-line ratios for a wide variety of active galactic nuclei, including those claimed to be shock heated. In the context of a Seyfert photoionization model, the entire range of
