The ROSAT PSPC spectrum of the Seyfert 2 galaxy NGC 4388.
ANTONELLI L.A., MATT G. and PIRO L.
Abstract (from CDS):
The ROSAT PSPC spectrum of the Seyfert 2 galaxy NGC 4388 is analyzed, with the aim to better understand the nature of the extended (a few kpc) soft X-ray emission discovered by the ROSAT HRI. Fitting the spectrum with an optically thin thermal model we find evidence for a metal abundance significantly lower than solar. We therefore argue that the emission is due at least in part to another component, maybe unresolved emission from compact sources.
