Resolution X-ray Spectroscopy with XMM-Newton and Chandra

NGC1808 is a nearby spiral galaxy that harbours an active central region with
an extent of 20 arcsec (i.e. 1 kpc). Previous X-ray and optical/NIR
observations have provided convincing evidence for the existence of a starburst
and an AGN. We present here preliminary results of the analysis of XMM-Newton
data. We show a weak high-resolution soft X-ray spectrum with only emission
lines typical of a starburst. Our analysis of the EPIC-pn spectrum shows two
thermal components, but there is an additional, hard X-ray power law tail that
is most likely due to an obscured active nucleus. Thus, our data show for the
first time the presence of emission from both components, AGN and starburst, in
one observation.
