Complex resonance absorption structure in the X-ray spectrum of IRAS 13349+2438

TL;DR: The spectrum obtained by the Reflection Grating Spectrometer (RGS) exhibits broad (FWHM - 1400 km/s) absorption lines from highly ionized elements including hydrogen- and helium-like carbon, nitrogen, oxygen, and neon, and several iron L - shell ions (Fe XVII - XX).

Complex resonance absorption structure in the X-ray spectrum of IRAS13349+2438

TL;DR: The spectrum obtained by the Reflection Grating Spectrometer (RGS) of the luminous infrared-loud quasar IRAS 13349+2438 was observed with the XMM-Newton Observatory as part of the Performance Verification program as mentioned in this paper.
Journal Article

EPIC status of calibration and data analysis

TL;DR: In this paper, the authors present XMM-Newton/EPIC spectra for the Laor et al. sample of Palomar Green (PG) quasars and find that a simple model, consisting of a broken power law (plus an iron line), provides a reasonable fit in most cases.
Journal ArticleDOI

Constraining the black hole mass and accretion rate in the narrow-line seyfert 1 galaxy re j1034)396

TL;DR: In this article, the authors present a comprehensive study of the spectrum of the narrow-line Seyfert 1 (NLS1) galaxy RE J1034+396, summarizing the information obtained from the optical to X-rays with observations from the William Herschel 4.2 m Telescope, the Hubble Space Telescope, Extreme Ultraviolet Explorer, ROSAT, ASCA, and BeppoSAX.
