XMM-Newton and broad iron lines
Fabian, A. C.
Iron line emission is common in the X-ray spectra of accreting black holes. When the line emission is broad or variable then it is likely to originate from close to the black hole. X-ray irradiation of the accretion flow by the power-law X-ray continuum produces the X-ray `reflection' spectrum which includes the iron line. The shape and variabilit…
X-rays from young stars: A summary of highlights from the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST)
Güdel, M.
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) is a survey of the nearest large star-forming region, the Taurus Molecular Cloud (TMC), making use of all instruments on board the XMM-Newton X-ray observatory. The survey, presently still growing, has provided unprecedented spectroscopic results from nearly every observed T Tauri…
Extragalactic archeology in integrated light: A test case with NGC 4030
Peletier, R.; Ocvirk, P.; Lançon, A.
We reconstruct the age-velocity distribution of the central region of the Sbc galaxy NGC4030, by applying STECKMAP to very high quality WHT/ISIS data. We find that the main component is a relatively young (≈ 2 Gyr) bulge with a ≈ 100 km/s velocity dispersion. The best fit solution also shows a superimposed young, kinematically cold (σ_{v}∼ 30 km/s…
The X-ray source population of the Andromeda galaxy M 31
Pietsch, W.
First studies of the X-ray source population of M 31 were performed with the Einstein Observatory and ROSAT. High resolution Chandra Observatory images not only spatially resolved the center area but also supernova remnants (SNRs) in the galaxy. Source catalogues of restricted areas were presented with high astrometric accuracy. Also luminosity fu…
Toward an unbiased sample of X-ray selected normal galaxies outside the local Universe
Georgakakis, A.
This paper shows that our understanding of the statistical properties of X-ray selected normal galaxies (e.g. X-ray luminosity function) can be significantly improved by combining a wide-area XMM-Newton survey with the moderare resolution and high S/N optical spectroscopy of the SDSS. Such a combined dataset has the potential to minimise uncertain…
Results and perspectives of young stellar object long look programs
Sciortino, S.
Both Chandra and XMM-Newton have performed long look programs for studying the YSO physics. I will discuss recent results on the controversial issue of Class 0 YSO X-ray emission, the observational evidence of magnetic funnels interconnecting the YSO with its circumstellar disk and the Fe 6.4 keV fluorescent line emission and its origin. While rec…
The XMM-LSS cluster sample and its cosmological applications: Prospects for the XMM next decade
Pierre, M.; Pacaud, F.; Melin, J. B. +1 more
The well defined selection function of the XMM-LSS surveys enables a simultaneous modelling of the observed cluster number counts and of the evolution of the L_X-T_X relation. We present results pertaining to the first 5 deg2 for a well controlled sample comprising 30 objects: they are compatible with the WMAP3 parameter set along with …
XMM-Newton: The next decade
Schartel, N.
Some key numbers about the XMM-Newton users, usage of the mission and the scientific outcome are provided. The background for selecting the topic, the preparation work, the organization and the corresponding committees are briefly described.
XMM-Newton operations beyond the 10-year design lifetime
Parmar, A. N.; Schartel, N.; Metcalfe, L. +2 more
In preparation for XMM-Newton operations beyond the 10-year design lifetime ESA instigated an independent review of all aspects of the mission. Unsurprisingly, the review found that the scientific interest in extending the mission is very high and likely to remain so in the foreseeable future. Most importantly, all the elements of the XMM-Newton m…
X-ray spectroscopy of early-type stars: The present and the future
Nazé, Y.; Rauw, G.; Oskinova, L. M.
XMM-Newton and Chandra have boosted our knowledge about the X-ray emission of early-type stars (spectral types OB and Wolf-Rayet). However, there are still a number of open questions that need to be addressed in order to fully understand the X-ray spectra of these objects. Many of these issues require high-resolution spectroscopy or monitoring of …
