The XMM–Newton view of Mrk 3 and IXO 30
We present the analysis of the XMM-Newton EPIC pn spectrum of the Seyfert 2 galaxy, Mrk 3. We confirm that the source is dominated by a pure Compton reflection component and an iron Kα line, both produced as reflection from a Compton-thick torus, likely responsible also for the large column density (1.36 −0.04 × 10 24 cm) which is pierced by the primary powerlaw only at high energies. A low inc...

متن کاملA polarimeter for IXO
The X-ray POLarimeter (XPOL) is an instrument that will fly on-board the International X-ray Observatory (IXO). We will describe the XPOL setup in IXO and we will compare the IXO requirements with the actual prototype performance. The environmental tests performed on the XPOL prototype (thermo-vacuum, vibration and heavy ions irradiation) show that this technology is ready for a space applicati...
متن کاملSpectral diagnostics for IXO
IXO with its high throughput and spectral resolution will allow X-ray spectroscopy to become a standard working horse for astrophysics. The grating spectrometers on Chandra and XMM-Newton have opened the field, but due to their limited effective area only for the brightest sources and due to the way that gratings work only for point sources or very compact extended sources. With IXO, the effect...
متن کاملASCA observations of Mrk 1040 & MS 0225 . 5 + 3121 3
We present ASCA observations of the Seyfert 1 galaxies Mrk 1040 and MS 0225.5+3121. Mrk 1040 was found to have decreased in ux by almost a factor of 4 since an EXOSAT observation 10 years ago. The energy spectrum of Mrk 1040 displays complexity both at soft energies (below 0.8 keV) and at hard energies (6{7 keV). The latter is readily interpreted as uorescent K emission from cold iron expected ...
