Fig. 3.


Top panel: continuum image obtained with ALMA at 350 GHz. The GRB afterglow is clearly seen in the centre of the image. Several other faint objects can be seen within the field-of-view, which measures 15″ × 15″. North is up and East is to the left. Centre panel: Spitzer image of the field in the 3.6 μm band, showing a slightly larger region. The box indicates the area of the upper figure. Sources S1 and S4 are detected. Bottom panel: late deep image obtained with FORS2 at VLT in the Rspecial band. Whereas ALMA sources S2, and S3 have no corresponding optical counterparts, S4 could be part of a nearby spiral galaxy to the South West and S1 is marginally detected.
