/ Abstract
We present measurements of the mean mid-infrared to submillimetre flux densities of massive (M_* ≳ 10^(11) M_⊙) galaxies at redshifts 1.7 2 (spheroid-like) population may be forming stars at a median [interquartile] SFR = 14[9, 20] M_⊙ yr^(−1), if at all. Finally, we show that star formation is a plausible mechanism for size evolution in this population as a whole, but find only marginal evidence that it is what drives the expansion of the spheroid-like galaxies.
