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…
Multiple Weak Deflections and the Detection of Flattened Halos with Galaxy-Galaxy Lensing
C. O. Wright, T. G. Brainerd
We investigate the occurrence of multiple weak deflections in deep data sets which are used to detect galaxy-galaxy lensing. Using the galaxies in the HDF (North) for which both re…
Anisotropic Galaxy-Galaxy Lensing
T. G. Brainerd, C. O. Wright
We investigate the weak lensing shear due to dark matter galaxy halos whose mass distributions, as projected on the sky, are nearly elliptical. The shear pattern due to these halos…
Gravitational Lensing by NFW Halos
Candace Oaxaca Wright, Tereasa G. Brainerd
We investigate the gravitational lensing properties of dark matter halos with Navarro, Frenk & White (NFW) density profiles and derive an analytic expression for the radial depende…
The Clustering of Faint Galaxies on Small Angular Scales
Tereasa G. Brainerd, Casey J. Law, James Brauher +2
We present a preliminary measurement of the angular clustering of faint () field galaxies in which we concentrate on the behavior of on small angular scales ($θ\ls…
