XMM-Newton observations of the heavily absorbed Seyfert 1 galaxy IC 4329A
K. C. Steenbrugge, J. S. Kaastra, M. Sako +5
We detect seven distinct absorbing systems in the high-resolution X-ray spectrum of the Seyfert 1 galaxy IC 4329A, taken with XMM-Newton. Firstly we detect absorption due to cold g…
X-ray/UV campaign on the Mrk 279 outflow: density diagnostics in Active Galactic Nuclei using O V K-shell absorption lines
J. S. Kaastra, A. J. J. Raassen, R. Mewe +6
One of the main problems in modeling the ionised outflows in Active Galactic Nuclei is the unknown distance of the outflowing wind to the central source. Only if the density is kno…
High Resolution X-ray Spectroscopy of Seyfert 2 Galaxies
S. M. Kahn, A. Kinkhabwala, M. Sako +6
X-ray spectroscopy of Seyfert 2 galaxies provides an excellent probe of the circumnuclear environment in active galactic nuclei. The grating experiments on both Chandra and XMM-New…
Stellar Coronae with \textit{XMM-Newton} RGS. II. X-ray Variability
M. Audard, M. Guedel, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy of flares with the Reflection Grating Spectrometers on board the \textit{XMM-Newton} satellite are reviewed. Rotational modu…
