Constraints on Field Galaxy Halos from Weak Lensing and Satellite Dynamics
Tereasa G. Brainerd
Here I summarize constraints on the nature of the dark matter halos of field galaxies that have been obtained from the most recent investigations of (i) weak galaxy-galaxy lensing…

Concordance between the Dynamics of Satellite Galaxies in the 2dFGRS and Lambda-CDM
Tereasa G. Brainerd
We compute the velocity dispersion profile, \sigmav(r_p), for satellites of host galaxies in the Two Degree Field Galaxy Redshift Survey (2dFGRS) and in the Lambda-CDM GIF simulati…

The Effects of Multiple Weak Deflections in Galaxy-Galaxy Lensing
Tereasa G. Brainerd
The Hubble Deep Field (North) and the flanking fields are used investigate the occurrence of multiple weak lensing deflections along the line of sight in relatively deep imaging da…
