Swift J1644+5734: the EVN view
Journal article, 2016
A small fraction of Tidal Disruption Events (TDE) produce relativistic jets, evidenced by their non-thermal X-ray spectra and transient radio emission. Here we present milliarcsecond-resolution imaging results on TDE J1644+5734 with the European VLBI Network (EVN). These provide a strong astrometric constraint on the average apparent jet velocity
βapp < 0.27, that constrains the intrinsic jet velocity for a given viewing angle.
