Witnessing the birth of the red sequence: the physical scale and morphology of dust emission in hyper-luminous starbursts in the early Universe

I. Oteo, R. J. Ivison, M. Negrello +22

We present high-spatial-resolution ($\sim 0.12^{\prime \prime }$ or $\approx 800\mathrm{pc}$ at $z=4.5$) ALMA $870\mu$m dust continuum observations of a sample of 44 ultrared dusty star-formin…
