The Solar Orbiter SPICE instrument -- An extreme UV imaging spectrometer

The SPICE Consortium, :, M. Anderson +88

The Spectral Imaging of the Coronal Environment (SPICE) instrument is a high-resolution imaging spectrometer operating at extreme ultraviolet (EUV) wavelengths. In this paper, we p…

Fe XXV and Fe XXVI lines from low velocity, photoionised gas in the X-ray spectra of AGN

Stefano Bianchi, Giorgio Matt, Fabrizio Nicastro +2

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 con…

Absorption spectra of Fe L-lines in Seyfert 1 galaxies

J. Dubau, D. Porquet, O. Z. Zabaydullin

Absorption L-lines of iron ions are observed, in absorption, in spectra of Seyfert 1 galaxies by the new generation of X-ray satellites: Chandra (NASA) and XMM-Newton (ESA). Lines…

XMM-Newton observation of the Seyfert 1 ESO 198-G24

D. Porquet, J. S. Kaastra, K. L. Page +3

We present the results from an XMM-Newton observation (January 24, 2001) of the bright Seyfert 1 galaxy ESO 198-G24 (z=0.045). We found that this Seyfert has an intrinsic 2-10 keV…

X-ray powerful diagnostics for highly-ionized plasmas: He-like ions

D. Porquet, R. Mewe, J. S. Kaastra +2

The calculations of the ratios of the Helium-like ion X-ray lines from C V to Si XIII are revisited in order to apply the results to density, temperature and ionization process dia…

Helium-like triplet diagnostics

Jacques Dubau, Delphine Porquet

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. Nowaday…
