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 …
Using X-ray observations to identify the particle acceleration mechanisms in VHE SNRs and ``dark'' VHE sources
Pühlhofer, G.
Very high energy (VHE) γ-ray observations have proven to be very successful in localizing Galactic acceleration sites of VHE particles. Observations of shell-type supernova remnants have confirmed that particles are accelerated to VHE energies in supernova blast waves; the interpretation of the γ-ray data in terms of hadronic or leptonic particle …
A scientific case for XMM-Newton continuation
McBreen, B.; Schartel, N.
The presentations made at the workshop ``XMM-Newton: The Next Decade'', held at ESAC from 4th to the 6th of July 2007, contained an overwhelming amount of new results and well justified scientific questions that can be addressed by observations with XMM-Newton. XMM-Newton has over the next decade a solid scientific case. Given the high impact of X…
Planned and serendipitous surveys with XMM-Newton
Watson, M. G.
This article compares and contrasts the virtues of planned (and normally contiguous) surveys with XMM-Newton and the XMM-Newton serendipitous sky survey and discusses various ways in which both the quality and efficiency of contiguous surveys with XMM-Newton could potentially be improved.
