A new observation of the tidal disruption candidate 2MASX 1446+68

In 2016 XMMNewton detected a flare from the galaxy 2MASX 1446+68 during a slew.Optical spectra subsequently showed that the galaxy is nonactive and a goodcandidate for a tidal disruption event, where a star is shredded and consumed bya supermassive black hole. We monitored the evolution of the disruption withXMM and Swift finding a drop in Xray flux of a factor 20, while the UV hasremained high and constant. This is the first event where the Xray flux fadesbefore the UV and casts doubt on currently fashionable models which ascribe theUV/optical emission to reprocessing of the Xray flux. We ask for an XMMobservation in AO17 to continue to monitor the Xray and UV flux and obtain ahigh quality spectrum. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
