Galaxy‐Galaxy Lensing in the Hubble Deep Field: The Halo Tully‐Fisher Relation at Intermediate Redshift
A tangential distortion of background source galaxies around foreground lens galaxies in the Hubble Deep Field is detected at the 99.3% confidence level. An important element of our analysis is the use of photometric redshifts to determine distances of lens and source galaxies and rest-frame B-band luminosities of the lens …
