We present deep ground based imaging of the environments of five quasi-stellar objects (QSOs) that contain sub-damped Lyman α (sub-DLA) systems at z L * galaxies for four of the five fields within 10 arcsec of the QSO. In contrast to previous imaging surveys of DLA systems at these redshifts, which indicate a range of morphological types and luminosities for the host galaxies of the systems, the galaxies we detect in these sub-DLA fields appear to be luminous (L ≳ L ★ ). In the case of the… Expand
