The Effect of Tidal Stripping on Composite Stellar Populations in Dwarf Spheroidal Galaxies
Laura V. Sales, Amina Helmi, Giuseppina Battaglia
We use N-body simulations to study the effects of tides on the kinematical structure of satellite galaxies orbiting a Milky Way-like potential. Our work is motivated by observation…
Orbital Eccentricity as a probe of Thick Disk Formation Scenarios
Laura V. Sales, Amina Helmi, Mario G. Abadi +7
We study the orbital properties of stars in four (published) simulations of thick disks formed by: i) accretion from disrupted satellites, ii) heating of a pre-existing thin disk b…
Disk galaxies at z=2 in OWLS
Julio F. Navarro, Laura V. Sales, Joop Schaye +2
We use the OWLS (OverWhelmingly Large Simulations) set of cosmological Nbody/gasdynamical simulations to study the properties of simulated galaxies at z=2. We focus on the effect o…
The Origin of Extended Disk Galaxies at z=2
Laura V. Sales, Julio F. Navarro, Joop Schaye +4
Galaxy formation models typically assume that the size and rotation speed of galaxy disks are largely dictated by the mass, concentration, and spin of their surrounding dark matter…
