Yu-Han Yang (U Rome), Eleonora Troja (U Rome), and Rosa Becerra (U Rome) report on behalf of the ERC BHianca team:
A further analysis was performed on the VLT/X-shooter spectrum reported by Yang et al. (GCN 39561). Whereas no significant features are visible in the VIS and NIR arms, we note the presence of absorption features at the edge of the UVB spectrum, consistent with Fe II (2600, 2587, 2383, 2374, 2344) at redshift z=1.131 as reported by Izzo et al. (GCN 39564). We therefore confirm this as the likely redshift of the EP transient.
