ROSAT and ASCA observations of the high X-ray luminosity starburst galaxies, NGC3310 and NGC3690
Abstract
We present preliminary ROSAT and ASCA results of the two high X-ray luminosity (Lx~1041-1042ergss^{-1}) starburst galaxies, NGC3310 and NGC3690. The ROSAT HRI observations show clearly a double component in NGC3690 while in NGC3310 the emission is also extended (~4kpc). We have fitted their spectra with a two component Raymond-Smith model or a power-law plus Raymond-Smith model. The temperature of the hard component is 7-10 keV (or a photon index of 1.5-1.8) and of the soft component 0.7-0.9 keV. These values are cosistent with the X-ray spectra of the prototypical starburst galaxies M82 and NGC253.
