The X-ray nature of the low luminosity Seyfert 2 galaxy NGC 7590
Abstract
Observations have detected a class of X-ray unabsorbed Seyfert 2 galaxies (NH<10^22 cm^-2). Interesting results have been obtained recently towards whether these sources may genuinely lack a broad-line region, in contrast to the standard unification model. However, only few objects have yet been securely identified. Seyfert 2 galaxy NGC 7590 was previously identified as X-ray unobscured based on ASCA data. New XMM images have shown its X-ray emission is dominated by extended component from the host galaxy and an off-nuclear ULX. The nature of the nuclear X-ray emission remains unclear due to strong contamination. With its superb spatial resolution, Chandra exposure would enable us the first time to detect the nuclear X-ray emission, and to measure the nuclear obscuration if existed.
