Dark Halo Scaling from Galaxy-Galaxy Lensingw of the mass distribution in galaxies implies the existence of a dark halo which extends far beyond the radius at which dynamical tracers can be observed. Gravitational lensing by galaxies offers the possibility to trace the halo profile to radii beyond ,~ 30.. kpc and may become the most sensitive

Galaxy-Galaxy Lensing in the Hubble Deep Field: the Halo Tully-Fisher Relation at High Redshiftt luminosities of galaxies. We detect a lensing signal at the ~ 98% confidence level from only 468 galaxies. Preliminary results suggest that the lensing galaxies in the HDF at a typical redshift of ~ 1.2 follow a Tully-Fisher-like relation with dark matter halo circular velocities of 200 ± 50 km s.

Bimodality of Freeman’s Lawal surface brightnesses is found to be bimodal. The bimodality is particularly significant at . because obscuration is not a problem and because the high surface brightness galaxies are redder than the low surface brightness galaxies so the bifurcation is greater. The bimodality signal is especially
