(Abridged) We present here a long (100ks) XMM-Newton follow-up of the Seyfert 1.8 galaxy ESO113-G010 performed in November 2005, in order to study over a longer time-scale its main X-ray properties....

A prominent relativistic iron line in the Seyfert 1 MCG-02-14-009 (2005)
I report the discovery of a prominent broad and asymmetrical feature near 6.4 keV in the Seyfert 1 MCG-02-14-009 (z=0.028) with XMM-Newton/EPIC. The present short X-ray observation (PN net exposure...
Repeated X-ray Flaring Activity in Sagittarius A* (2005)
Belanger, Guillaume, Goldwurm, Andrea, Melia, Fulvio, Yusef-Zadeh, Farah, Ferrando, Philippe, Porquet, Delphine, ...
Investigating the spectral and temporal characteristics of the X-rays coming from Sagittarius A* (Sgr A*) is essential to our development of a more complete understanding of the emission mechanisms...

Fe XXV and Fe XXVI lines from low velocity, photoionised gas in the X-ray spectra of AGN (2004)
Bianchi, Stefano, Matt, Giorgio, Nicastro, Fabrizio, Porquet, Delphine, Dubau, Jacques
We have calculated the equivalent widths of the absorption lines produced by Fe XXV and Fe XXVI in a Compton-thin, low-velocity photoionised material illuminated by the nuclear continuum in AGN. The...

We present an XMM-Newton observation of the radio-quiet quasar Q0056-363 (z=0.162). This is the first time that this quasar is observed in the hard X-ray range (above 2 keV). We find that Q0056-363...
Far-UV FUSE spectra of peculiar magnetic cataclysmic variables (2003)
Mouchet, Martine, Bonnet-Bidaud, Jean-Marc, Roueff, Evelyne, Abada-Simon, Meil, Beuermann, Klaus, De Martino, Domitilla, ...
We present far-UV spectra of the three magnetic cataclysmic variables (MCVs) BY Cam, V1309 Ori and AE Aqr obtained with the FUSE satellite. These MCVs have revealed strongly unusual NV and CIV UV...
Helium-like triplet diagnostics (2002)
Dubau, Jacques, Porquet, Delphine
The 1s2-1s2l lines are the most intense He-like ions lines. They are used as spectroscopic diagnostics for solar active regions as well as for different laboratory plasmas. Nowadays, it exits very...
Porquet, Delphine, Dubau, Jacques
We present He-like line ratios (resonance, intercombination and forbidden lines) for totally and partially photoionized media. For solar plasmas, these line ratios are already widely used for density...

The Warm Absorber constrained by the coronal lines in Seyfert 1 galaxies (1998)
Porquet, Delphine, Dumont, Anne-Marie, Collin, Suzy, Mouchet, Martine
We present results of the photoionization code IRIS, which calculates the spectrum emitted by the Warm Absorber (WA) in Seyfert 1 galaxies for a large grid of parameters (density, column density,...
