HST cutout images in the F606W, F814W, F125W and F160W broad band filters for three starbursts in the COSMOS-CANDELS field. As explained in the text, the second galaxy has a photometric redshift of 0.92, while the third has a SFR a factor of three above the main sequence at the same redshift z = 0.74, but clearly shows a merger morphology (in spite of its edge-on profile). The multi-wavelength comparison shows that clumps become brighter at shorter wavelengths, thus they likely represent merger-induced young stellar associations rather than old pre-existing structures. The IDs shown in the right part of the figure come from Laigle et al. (2016).
