The formation of shell galaxies similar to NGC 7600 in the cold dark matter cosmogony
Andrew P. Cooper, David Martinez-Delgado, John Helly +6
We present new deep observations of 'shell' structures in the halo of the nearby elliptical galaxy NGC 7600, alongside a movie of galaxy formation in a cold dark matter universe (a…
The GALEX Arecibo SDSS Survey. IV. Baryonic Mass-Velocity-Size Relations of Massive Galaxies
Barbara Catinella, Guinevere Kauffmann, David Schiminovich +12
We present dynamical scaling relations for a homogeneous and representative sample of ~500 massive galaxies, selected only by stellar mass (>10^10 Msun) and redshift (0.025<z<0.05)…
The initial mass spectrum of old globular clusters in dwarf galaxies
J. M. Diederik Kruijssen, Andrew P. Cooper
We test whether the masses of old globular clusters (GCs) in dwarf galaxies are consistent with the same initial mass spectrum as young massive clusters (YMCs) in nearby star-formi…
On the Effects of Line-of-Sight Structures on Lensing Flux-ratio Anomalies in a LCDM Universe
D. D. Xu, Shude Mao, Andrew Cooper +4
The flux-ratio anomalies observed in multiply-lensed quasar images are most plausibly explained as the result of perturbing structures superposed on the underlying smooth matter di…
Clues to the "Magellanic Galaxy" from Cosmological Simulations
Laura V. Sales, Julio F. Navarro, Andrew P. Cooper +3
We use cosmological simulations from the Aquarius Project to study the orbital history of the Large Magellanic Cloud (LMC) and its potential association with other satellites of th…
The population of Milky Way satellites in the LambdaCDM cosmology
Andreea S. Font, Andrew J. Benson, Richard G. Bower +11
We present a model for the satellites of the Milky Way in which galaxy formation is followed using semi-analytic techniques applied to the six high-resolution N-body simulations of…
