Abstract We measure the alignment of galaxy ellipticities in the local Universe over a range of scales using digitized photographic data from the SuperCOSMOS Sky Survey. We find for a magnitude cut of b J<20.5, corresponding to a median galaxy redshift of z≈0.1, and 2×106 galaxies, that the galax...
