Absorbed central engine revealed in Mrk 1239

Deep X-ray observations of the NLS1 galaxy Mrk 1239 reveal complete absorption of the AGN continuum below 3 keV by a 10^23.5 cm^-2 neutral medium. Timing analysis shows no variability in soft X-rays, indicating a large-scale origin. A strong flare seen in hard X-rays is consistent with blurred reflection off the accretion disc. Collisionally ionized and photoionized emission may originate from an outflow crashing into surrounding material.
