X-ray spectroscopy of the LINER M81

GT Detailed Xray spectral information will help to distinguish between theemission mechanisms present in this bright LINER. If it contains a .dwarf. AGN,it should show a compact, variable source whose Xray emission has a nonthermalpowerlaw form. It may also show strong Fe Kalpha line emission produced byfluorescence in cold matter. On the other hand, nuclear starbursts arefrequently extended over kpac scales and are expected to show thermal spectracharacterised by coronal Xray emission lines. The high spectral resolution ofthe RGS, combined with the long exposure time, will produce spectra of unprunprecedented detail. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
