Multi-wavelength light curve evolution of J2344, with the unabsorbed 0.2−2 keV fluxes (top panel) and the optical and UV fluxes (middle). Triangular data points denote 3σ upper limits on the flux. The horizontal dashed red line in the X-ray light curve panel denotes the 3σ upper limit on the 0.2−2 keV flux inferred from the non-detection of J2344 in eRASS1 (Homan et al. 2023), approximately 200 days before optical peak. The radio evolution (bottom panel) is well described by an expanding synchrotron-emitting region from a single ejection of material, consistent with an outflow launched by a non-relativistic TDE (Goodwin et al. 2024).
