Scientific paper

We propose two ACIS-S observations of the fading X-ray flare of the galaxy J0952+21 and one ACIS-S observation of the galaxy J1241+44. J0952+21 is unique in showing a very intense optical and NIR emission-line light echo in response to a high-energy flare which we also detected in the optical, NUV and NIR continuum (Komossa et al. 2008). The flare was likely caused by a stellar tidal disruption event. J1241+44 shows a similarly unusual optical emission-line spectrum, and we suspect a similar mechanism at work as in J0952+21.
