摘要：

The XMM-Newton first-light image revealed X-ray point sources which show heavily absorbed power-law spectra. The spectral indices and the probable identification of a radio counterpart for the brightest source suggest AGN shining through the interstellar gas of the Large Magellanic Cloud (LMC). The column densities derived from the X-ray spectra in combination with Hi measurements will allow to draw conclusions on Hi to Na ratios in the LMC and compare these with values found for the galactic plane.
