Broad Iron Lines in AGN and X-ray Binaries

Several AGN and black hole X-ray binaries show a clear very broad iron line which is strong evidence that the black holes are rapidly spinning. Detailed analysis of these objects shows that the emission line is not significantly affected by absorption and that the source variability is principally due to variation in amplitude of a power-law. Underlying this is a much less variable, relativisti...

An XMM-Newton survey of broad iron lines in AGN

We report on the iron Kα line properties of a sample of Seyfert galaxies observed with the XMM-Newton EPIC pn instrument. Using a systematic and uniform analysis, we find that complexity at iron-K is extremely common in the XMMNewton spectra. Once appropriate soft X-ray absorption, narrow 6.4 keV emission and associated Compton reflection are accounted for, ∼ 75 % of the sample show an improvem...

FeXVII X-ray lines in solar coronal and laboratory plasmas

Theoretical intensities of the Fe xviiX-ray lines due to transitions 2p6 − 2p53d (near 15 Å) and 2p6 − 2p53s (near 17 Å) are presented, and compared with solar flare and active region spectra. The ratio of the 15 Å lines to the 17 Å lines is a function of temperature Te, but for solar spectra this is not of practical use because of the resonance scattering of the intense 15.015 Å line. Instead ...

X-ray Spectroscopy of QSOs with Broad Ultraviolet Absorption Lines

For the population of QSOs with broad ultraviolet absorption lines, we are just beginning to accumulate X-ray observations with enough counts for spectral analysis at CCD resolution. From a sample of eight QSOs [including four Broad Absorption Line (BAL) QSOs and three mini-BAL QSOs] with ASCA or Chandra spectra with more than 200 counts, general patterns are emerging. Their power-law X-ray con...

X-ray emission from Seyfert 2 galaxies with optical polarized broad lines

We analyze the 0.5−10 keV spectra of six Seyfert 2 galaxies observed with the X-ray satellite ASCA: Mrk 3, Mrk 348, Mrk 1210, Mrk 477, NGC 7212, and Was 49b. These galaxies were selected based on their possession of optical polarized broad lines. In the 2−10 keV band, their spectra are heavily absorbed, with 2−10 keV absorption-corrected X-ray luminosities ranging from 10 to 10 ergs s−1. The ob...
