The cluster lens ACO 1703: redshift contrast and the inner profile
Prasenjit Saha, Justin I. Read
ACO 1703 is a cluster recently found to have a variety of strongly lensed objects: there is a quintuply-imaged system at z=0.888 and several other lensed objects from z=2.2 to 3.0…
Detecting the Milky Way's Dark Disk
T. Bruch, J. Read, L. Baudis +1
In LambdaCDM, massive satellites are dragged into the disk-plane by dynamical friction where they dissolve into a stellar thick disk and a more massive dark matter disk. The distin…
Thin, thick and dark discs in LCDM
J. I. Read, G. Lake, O. Agertz +1
In a LCDM cosmology, the Milky Way accretes satellites into the stellar disc. We use cosmological simulations to assess the frequency of near disc plane and higher inclination accr…
The Causes of Halo Shape Changes Induced by Cooling Baryons: Disks Versus Substructures
Victor P. Debattista, Ben Moore, Thomas Quinn +5
Cold dark matter cosmogony predicts triaxial dark matter halos, whereas observations find quite round halos. This is most likely due to the condensation of baryons leading to round…
Radial density profiles of time-delay lensing galaxies
J. I. Read, P. Saha, A. V. Maccio
We present non-parametric radial mass profiles for ten QSO strong lensing galaxies. Five of the galaxies have profiles close to , while the rest are closer to r…
Two strong-lensing clusters confront universal dark-matter profiles
P. Saha, J. I. Read, L. L. R. Williams
In the galaxy clusters SSDS J1004+411 and ACO 1689, a large number of multiply-imaged background objects have recently been observed. We use these data to map the projected mass di…
