Global structure and kinematics of stellar haloes in cosmological hydrodynamic simulations
Ian G. McCarthy, Andreea S. Font, Robert A. Crain +3
We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) suite of cosmological hydrodynamical simulations to study the global structure and kinematics of stellar sp…
Elliptical galaxy masses out to five effective radii: the realm of dark matter
A. J. Deason, V. Belokurov, N. W. Evans +1
We estimate the masses of elliptical galaxies out to five effective radii using planetary nebulae and globular clusters as tracers. A sample of 15 elliptical galaxies with a broad…
Mock weak lensing analysis of simulated galaxy clusters: bias and scatter in mass and concentration
Yannick M. Bahé, Ian G. McCarthy, Lindsay J. King
(Abridged) We quantify the bias and scatter in galaxy cluster masses and concentrations derived from an idealised mock weak gravitational lensing (WL) survey, and their effect on t…
Quantifying the effect of baryon physics on weak lensing tomography
Elisabetta Semboloni, Henk Hoekstra, Joop Schaye +2
We use matter power spectra from cosmological hydrodynamic simulations to quantify the effect of baryon physics on the weak gravitational lensing shear signal. The simulations cons…
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…
Cosmological simulations of the formation of the stellar haloes around disc galaxies
Andreea S. Font, Ian G. McCarthy, Robert A. Crain +4
We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) suite of cosmological hydrodynamical simulations to study the formation of stellar spheroids of Milky Way-m…
