摘要：

We show that the strong iron line observed in the Ariel V X-ray spectrum of the Seyfert galaxy NGC 5548 may be due to recombination-line emission in a highly photo-ionized gas. This gas must lie within 3 x 1016cm of the source of the continuum emission, and provides a direct handle on conditions deep within the broad-line region of the nucleus. The iron line is the closest feature yet observed to the continuum source. © Royal Astronomical Society.
