X-ray and optical properties of X-ray sources in the 13hr XMM-Newton/Chandra deep survey
Page, M. J.; Sasseen, T.; Mason, K. O. +8 more
The 13hr XMM-Newton/Chandra deep survey is the first of two extremely deep XMM-Newton fields observed by the XMM-OM consortium. A 120 ks Chandra mosaic, covering 0.2 deg2, provides sensitive, confusion-free point source detection with sub-arcsecond positions, while the 200 ks XMM-Newton observation provides high quality X-ray spectrosco…
XMM-Newton observation of the galactic centre - evidence against the X-ray reflection nebulae model?
Costantini, E.; Hasinger, G.; Predehl, P. +1 more
We present preliminary results of a 50 ksec \XMM observation of the Galactic Centre. Due to the excellent spectral resolution of \XMM combined with its high throughput at energies even beyond 7 keV, the iron line complex could be resolved into individual components (neutral, ionized, both in Kalpha and Kbeta ) in the spectra of a number of sources…
The XMM-Newton serendipitous source catalogue
Pietsch, W.; Motch, C.; Boller, Th. +17 more
We describe the production, properties and scientific potential of the XMM-Newton catalogue of serendipitous X-ray sources. The first version of this catalogue is nearing completion and is planned to be released in early 2003.
The source content of low galactic latitude XMM-Newton surveys
Motch, C.; Guillout, P.; Herent, O.
We present results from a project conducted by the Survey Science Center of the XMM-Newton satellite and aiming at the identification and characterisation of serendipitous EPIC sources at low galactic latitudes. Deep multi-colour optical imaging and spectroscopic observations have been obtained in the framework of several observing campaigns carri…
Deep XMM survey of M33
Pietsch, W.; Haberl, F.; Ehle, M. +2 more
In an XMM raster observation of the bright local group spiral galaxy M33 we study the population of X-ray sources (X-ray binaries, supernova remnants, super-shells) down to a 0.5-10 keV luminosity of \oergs{35} - more than a factor of 10 deeper than earlier ROSAT observations. EPIC spectra and hardness ratios are used to distinguish between differ…
XMM-Newton view of the Hubble Deep Field-North and Groth-Westphal strip regions
Griffiths, R. E.; Miyaji, T.; Lumb, D. +2 more
We report the progress on our analysis of two deep XMM observations in the areas of Hubble Deep Field-North and the Groth-Westphal Strip field. We present the source detection method, Monte-Carlo simulation on source detection, and our preliminary Log N - Log S relations. Comparing these two fields and other fields in literature, we find up to ∼ 3…
The XMM-Newton Survey Science Centre Medium Sensitivity Survey
Pérez-Fournon, I.; Page, M. J.; Barcons, X. +5 more
We present preliminary results on the XMM-Newton Survey Science Centre medium sensitivity survey, with 0.5-4.5 keV flux limit 2x 10-14 erg cm-2 s-1. At present, 19 fields have been examined with a total of 239 X-ray sources. Identifications for about 2/3 of these reveal that type 1 AGN dominate, but type 2 AGN, abs…
XMM-Newton local bubble and galactic halo survey

Optical identifications in the Marano field XMM-Newton survey
Hasinger, G.; Mignoli, M.; Zamorani, G. +4 more
The ``Marano field'', a deep optical quasar survey field, has been observed by the XMM Newton EPIC camera with 16 overlapping pointings totalling at ~ 120 ksec integration time. Source detection in the merged observations resulted in more than 600 X-ray sources. Here we present the status of optical follow up observations which were undertaken to …
Structure of a simple sunspot from the inversion of IR spectral data
Krupp, N.; Woch, J.; Solanki, S. K. +5 more
Analysis of spectral data of two neighboring infrared lines, Fe i 15648.5 Å (g = 3) and Fe i 15652.9 Å (g_eff = 1.53) are carried out for a simple sunspot when it was near the solar disk center (mu = 0.92), to understand the basic structure of sunspot magnetic field. Inversions of Stokes profiles are carried out to derive different atmospheric par…
