"This work uses very deep imaging from both Hubble and the Subaru telescope to establish a beautiful correlation between the sizes and elongation of galaxies when the universe was only 10% of its present age. The very high resolution Hubble images are used to show that the elongation of the galaxy images seen in the ultra sensitive Subaru imaging is due to overlap multiple galaxies. This research clearly shows the prevalence of galaxy merging in building up the earliest galaxies and promoting more rapid formation of stars."
