Upper limits on the radio luminosity of XMMSL2 J1446+68 (black triangles) compared with other TDEs and plotted against observed time since disruption or discovery. The coloured points are radio detections of TDEs from the literature (Zauderer et al. 2011, 2013; Berger et al. 2012; Eftekhari et al. 2018; Cenko et al. 2012b; Pasham et al. 2015; Brown et al. 2015; Irwin et al. 2015; Perlman et al. 2017; Alexander et al. 2016, 2017; Mattila et al. 2018), while the grey triangles are upper limits from non-detections (Bower et al. 2013; van Velzen et al. 2013, 2019; Arcavi et al. 2014; Chornock et al. 2014; Blagorodnova et al. 2017; Blanchard et al. 2017, Alexander et al. 2019 and references therein). All upper limits are 5σ.
