Masao Sako,S. M. Kahn,Ehud Behar,Jelle Kaastra,A. C. Brinkman,Th. Boller,E. M. Puchnarewicz,R. L. C. Starling,Duane A. Liedahl,J. Clavel,Maria Santos-Lleo +10 more
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
M. Sako,S. M. Kahn,Etienne Behar,Jelle Kaastra,A. C. Brinkman,Th. Boller,E. M. Puchnarewicz,R. L. C. Starling,D. A. Liedahl,J. Clavel,Maria Santos-Lleo +10 more
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.

TL;DR: The first all-sky survey for cosmic sources of extreme-ultraviolet radiation has been carried out with the UK Wide Field Camera on ROSAT as mentioned in this paper, which yielded a catalogue of 383 relatively bright EUV sources, forming the WFC Bright Source Catalogue.
Journal Article
EPIC status of calibration and data analysis
Catherine Brocksopp,Rlc Starling,Patricia Schady,K. O. Mason,Encarni Romero-Colmenero,E. M. Puchnarewicz +5 more
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
E. M. Puchnarewicz,Keith O. Mason,Aneta Siemiginowska,Antonella Fruscione,Andrea Comastri,Fabrizio Fiore,I. Cagnoni +6 more
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.
