Constraining Dark Energy from Local Group dynamics
D. Benisty, A. -C. Davis, N. W. Evans
This Letter develops a method to constrain the Cosmological Constant from binary galaxies, focusing on the Milky Way and Andromeda. We provide an analytical solution to the two…

The dark matter halo concentration and stellar initial mass function of a CASSOWARY group
A. J. Deason, M. W. Auger, V. Belokurov +1
We exploit the group environment of the CAmbridge Sloan Survey Of Wide ARcs in the skY (CASSOWARY) z=0.3 lens J2158+0257 to measure the group dynamical mass as a complement to the…

Accurate Masses for Navarro-Frenk-White Dark Matter Haloes
N. W. Evans, J. An, A. Deason
We consider the problem of estimating the virial mass of a dark halo from the positions and velocities of a tracer population. Although a number of general tools are available, mor…
