Synthetic emission maps at time 156 kyr (1.87 t_cc). Top: for a single wavelength of 5 mm. Bottom: for all wavelengths. Distances on the axes are in parsec, unit of the colour bar are in Jansky. We integrated the density over the line of sight. We show the logarithm of the resulting 2D map as black contour. Distance are in parsec (corresponding to 38 s of arc at a distance of 5.5 kpc from the source).
