A Long Look at NGC 3783 with the XMM-Newton Reflection Grating Spectrometers
Ehud Behar, Andrew P. Rasmussen, Alexander J. Blustin +5
A long 280 ks observation of the Seyfert 1 galaxy NGC 3783 with XMM-Newton is reported. We focus on the oxygen line complex between 17 and 24 A as measured with the RGS spectromete…
Chandra LETGS and XMM-Newton observations of NGC 4593
K. C. Steenbrugge, J. S. Kaastra, A. J. Blustin +6
In this paper, we analyze spectra of the Seyfert 1 galaxy NGC 4593 obtained with the Chandra Low Energy Transmission Grating Spectrometer (LETGS), the Reflection Grating Spectromet…
Simultaneous UV and X-ray Spectroscopy of the Seyfert 1 Galaxy NGC 5548. I. Physical Conditions in the UV Absorbers
D. M. Crenshaw, S. B. Kraemer, J. R. Gabel +9
We present new UV spectra of the nucleus of the Seyfert 1 galaxy NGC 5548, which we obtained with the Space Telescope Imaging Spectrograph at high spectral resolution, in conjuncti…
Contrasting the UV and X-ray O VI Column Density Inferred for the Outflow in NGC 5548
Nahum Arav, Jelle Kaastra, Katrien Steenbrugge +4
We compare X-ray and UV spectroscopic observations of NGC 5548. Both data sets show O VI absorption troughs associated with the AGN outflow from this galaxy. We find that the robus…
Multiwavelength studies of the Seyfert 1 galaxy NGC7469. II - X-ray and UV observations with XMM-Newton
A. J. Blustin, G. Branduardi-Raymont, E. Behar +6
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-alpha emission line and the first-ever high…
XMM-NEWTON High Resolution Spectroscopy of NGC 5548
K. C. Steenbrugge, J. S. Kaastra, C. P. de Vries +1
We analyze a 137 ks exposure X-ray spectrum of the Seyfert 1 galaxy NGC 5548 obtained with the XMM-Newton Reflection Grating Spectrometer. Due to the long exposure time, the spectr…
